Best Food Writing 2010

  At dinner, I sliced off the end piece and held it up for everyone to see.

  “Holes!” Katie cried.

  “Holes!” Anne yelled.

  “Holy sh . . . ,” I started to yell.

  Charlie had been right. Switching to a levain was the key—but not to every door. The second slice had fewer holes than the first, and the one after that had none. In fact, the middle 80 percent of the boule was too dense and too moist. Still, it was the best loaf of bread I’d ever baked, and I was elated.

  The crumb had a rich, natural flavor, a bit tangy but not nearly as strong as a San Francisco sourdough, a result not only of the wild yeast and bacteria in the levain, but of the long, cool fermentation, which allowed time for the production of various organic compounds such as alcohols, esters, ketones, and aldehydes—scientists have identified over two hundred such compounds in a fermented dough—which even in their minuscule amounts provide the signature taste and smell that we associate with freshly baked artisan bread.

  The real treat, however, was the crust, extraordinarily sweet and bursting with flavor, and for once not rock-hard. If I could get the entire loaf to taste like the crust, I’d have the best bread on the planet. Of course, to make the crumb taste like the crust is physically impossible, for the crust—both its brown color and its unique, sweet flavor—is formed by a complex chemical process known as the Maillard reaction, which begins to take place at about 300 degrees Fahrenheit, a temperature that the surface of the bread can easily reach, but not the moist interior, which never rises above 212 degrees, the boiling point of water.

  During the Maillard reaction, proteins under high heat break down (or “denature”) and recombine with sugar molecules and all those wonderful products of fermentation to form dozens of new flavor compounds, which in turn break down to form even more compounds, hundreds in all, giving the crust a flavor as different from the crumb as toast (also a Maillard-reaction product) is to bread.

  For the first time, I had baked a loaf of bread that I didn’t feel I needed to apologize for. As I placed the replenished levain in the fridge, though, Anne pointedly asked, “What are you doing with that?”

  “I’m putting it in the refrigerator. What does it look like I’m doing with it?”

  “I mean next week. When we go on vacation.You’re not leaving it here, are you?”

  So it could creep out of the container and destroy another refrigerator?

  “Of course not,” I improvised, thinking this was like having a pet. “I’m bringing it with us. Got to make the bread.”

  Even on vacation.

  HOW TO MAKE PERFECT THIN AND CRISPY FRENCH FRIES

  By J. Kenji Lopez-Alt From seriouseats.com

  With an M.I.T. degree and a cooking resumé from some of Boston’s finest restaurants, it’s only natural that Kenji Lopez-Alt’s freelance food writing would focus on kitchen science, producing features like the Food Lab for goodeater.org and the Burger Lab for seriouseats.com.

  N .B. I apologize in advance for the length of this post. French fries are a pretty epic subject for me . . . .

  I’m gonna come right out and say something that I’m sure you won’t all openly agree with: McDonald’s french fries are great. At their best, they are everything a french fry should be: salty, crisp, light, and not greasy. Granted, you get the occasional odd franchise that lets ‘em sit under the heat lamp for a couple hours too long, but on the whole, I find it remarkable that the bigwigs have discovered a way to create a frozen fry that even a one armed eyeless chimp has trouble screwing up. And I know, because they’ve got one working the fry station at the franchise on my corner.

  To be absolutely honest, I’ve never been able to make fries as good as theirs (shhhhh!). Sure, my thick-cut pub-style fries are super-potatoey and fantastic, and when I’m in the mood for them, my seasoned steak fries can’t be beat, but for thin, super-crisp fries (I’m talking the kind that only appear in fast food restaurants and French bistros under the name frites)? I’m always better off running down to the take-out window than bothering to fry them myself at home.

  Until now.

  I’ve been literally giddy with the quality of the fries that have been coming out of my kitchen for the last two days. My wife won’t hear the end of it. Even my puppy is wondering why his owner keeps exclaiming “Holy s--t that’s good!” every half hour from the kitchen. I’ve cooked over 43 batches of fries in the last three days, and I’m happy to report that I’ve finally found a way to consistently reach crisp, golden Nirvana.

  The Anatomy of a Perfect Fry

  There are a few factors that go into making a perfect fry:

  Perfect Fry Factor #1: The exterior must be very crisp, but not tough.

  In order to achieve this crispness, the surface structure of a fry must be riddled with micro-bubbles. It’s these tiny crisp bubbles that increase the surface area of the fry, making it extra crunchy. Ideally, this layer should only be as thick as it needs to be to add crispness. Any thicker, and you start running into leathery territory.

  Perfect Fry Factor #2: The interior must be intact, fluffy, and have a strong potato flavor.

  Fries with a pasty, mealy, or gummy interior or even worse, the dreaded state known as “hollow-fry” (when the interior is missing entirely) are an automatic fail in my fry book.

  Perfect Fry Factor #3: The fry must be an even, light golden blond. Fries that are too dark or are spotty have an offputting burnt flavor that distracts from the potato. Light golden but perfectly crisp is how I want my fries to be.

  Perfect Fry Factor #4: The fry must stay crisp and tasty for at least as long as it takes to eat a full serving.

  Fries that comes straight out of the fryer are almost always perfectly crisp. The true test of a great fry is whether or not it remains crisp and edible a few minutes later after its been sitting on your plate. [ . . . ]

  So how does one going about achieving these goals? The traditional double fry method (once at low temp, then again at high temp) works, but it’s far from foolproof, and fails to meet all of the requirements I’ve set for a perfect fry. For one thing, the fries inevitably come out too brown—sometimes massively so. For another, they lose their crunch within a few minutes after coming out of the fryer. Clearly the method needs an overhaul. I suppose I could do what the McDonald’s Corporation did and spend millions of dollars researching exactly how to accomplish fry perfection time after time anywhere around the world, but unfortunately Serious Eats doesn’t pay me well enough to do that. I’m also understaffed, to say the least. So I decided to go with the next best alternative: steal their recipe.

  That’s much easier said than done.

  Hamburgling

  Anyone with a buck can get a batch of fully cooked McDonald’s fries, but I was after something more. I wanted to get fries from the store in their fully frozen state so that I could examine their surface for clues on how they were parcooked, as well as attempt to fry them myself at home to discover if there is any secret in the fry oil in the shops.

  I figured I’d just be able to walk into the store and order them straight from the cashier.

  “Welcome to McDonald’s, may I take your order?”

  “Yes Ma’am. I’d like a large fries please, hold the cooking.”

  “Excuse me?”

  I know she’s already said no in her head, but I press on just the same: “Um . . . I’d just like the frozen fries please.”

  “I’m sorry sir, we just don’t do that.”

  Time for some intimidation tactics: “Ok. Could I speak to the manager please?”

  “I am the manager.”

  Sh-t. I bring out the really big guns: “Listen, the thing is, my wife is pregnant—like really pregnant—and she sent me on a quest for McDonald’s french fries. But she only likes them really fresh, like straight out of the fryer fresh, so I figured I’d just get some frozen, and fry them for her at home. You know how it is. Women—no accounting for’em, right?”

  She rem
ains unimpressed, and needless to say, I go home fry-less, contemplating whether attempting to leverage an unborn, un-conceived son in exchange for a couple dozen frozen potato sticks is grounds for eternal damnation. Thank God I’m an atheist.

  In a last ditch effort, I appeal to my Facebook fans for some assistance, promising cold hard cash and full credit in this story to anyone who could get me a stash of frozen McDonald’s fries. Within 24 hours, I had received this email from a Grant Held:

  Kenji, you put forth an excellent challenge; I enjoy both challenges and your food writing immensely, so I came up with an excellent plan that worked the first try.

  Getting your frozen fries was simply a matter of finding the right fraternity man; one who had the ability to make up extemporaneous bullsh-t and the all important “charm factor.” Some would say possessing these attributes can help you get laid in college, but I plead The Fifth....

  The plan involved me printing out a fake list of items needed for a Scavenger Hunt sponsored by “The Simplot Foundation.” A “Mr. Simplot” had endowed an annual prize for the winning team of the scavenger hunt, which would be used to fund the “research projects of the members of the winning team each year.” (Members also had to belong to the Harold McGee Society and Order of Brillat-Savarin.)

  I walked into the McD’s on xxxxxxx. (The exact location has been removed because we don’t want to get the manager fired.)

  I had pre-printed a list of items for said made up “Scavenger Hunt.” (I basically Googled “Scavenger Hunt Lists” and added “Frozen McDonald’s french fries.”)

  I walked in, asked for the manager and explained the scavenger hunt. I said I needed 25 fries, which I was willing to pay for, but they had to be frozen. Her English was not ideal, so I spoke Spanish, and a young associate took kindly upon me and explained what I needed. The manager agreed, but thought I was asking for 25 FREE packages of cooked fries!!! And she was willing to give them to me!!! (She said my accent was great but my grammar was terrible . . . oh well . . . )

  I said I needed FROZEN fries, which really perplexed her, but my young McD’s associate friend explained the concept of a scavenger hunt and soon enough I was invited into the kitchen and she grabbed a handful of fries and placed them in the zip lock bag I brought with me.

  Grant, you are a genius amongst men, and I am forever in your debt.

  The handoff was made the next day, and I finally had a batch of frozen McDonald’s fries on which to operate.

  Deconstructing the Arches

  The first thing I noticed was the surface texture of the fries. They seemed smooth, but on closer inspection, I noticed that they were dotted with tiny tiny bubbles, indicating that they had definitely been fried at least once prior to arriving at the store. I measured them with calipers and found that they were precisely ¼ of an inch thick. A good size for optimizing crust to interior ratio.

  McDonald’s used to fry their potatoes in beef tallow, giving them extra flavor and making them extra crisp, but they stopped doing that years ago. But perhaps there’s still something magic about their oil? To test this, I fried up a batch of the frozen fries in 375°F peanut oil, letting them cook for about 3 minutes before draining, seasoning, and tasting.

  They were just as perfect as the fries at the store. That answers the first question: there is no magic in the oil. Something must be done to those potatoes during the pre-processing that makes them unique.

  For the next phase, I started doing some research and caught a lucky break by finding this article online, which essentially runs through the whole process of what goes on in a McDonald’s potato processing plant as told by LeAron Plackett, a thirteen-year-long employee. The parts that interested me most were on the second page:

  The fries are then flumed out of the A.D.R. room to the “blancher.” The blancher is a large vessel filled with one hundred and seventy degree water. The trip through the blancher takes about fifteen minutes.... After the fries leave the blancher, they are dried and then it’s off to the “fryer,” which is filled with one hundred percent vegetable oil. The oil is heated to three hundred and sixty five degrees and the fries take a fifty second dip before being conveyed to the “de-oiler shaker,” where excess oil is “shook off.”

  Bingo.

  So McDonald’s does indeed use a double fry method, but it’s far from the traditional one. Rather than a slow low temperature fry for the first round, the fries get dunked into very hot oil for only 50 seconds (the second fry is then carried out at the actual location). In addition to this, the potatoes get a pre-fry blanching step in hot water. What could the purpose of this be?

  To answer that question, it’s important to understand exactly what happens when a french fry is cooked.

  The Balance of Pectin, Starch, and Simple Sugars

  Like all plants and animals, potatoes are composed of cells. These cells are held together by pectin, a form of sugar that acts as a type of glue. These cells also contain starch granules—tiny sacs that resemble water balloons, as well as simple sugars. When these starch granules are exposed to water and heat, they begin to swell, eventually bursting, and releasing a shower of swollen starch molecules. Now the problem is, in order to get the ideal crust, all three of these elements must be in the proper balance, and the proper state. Too many simple sugars, and your potato will brown long before it crisps. If pectin has broken down too much before the starch granules have had a chance to burst and release their sticky innards, your potatoes will either fail to form a crust, will fall apart before it gets a chance to, or in the worst case will cook up completely hollow [ . . . ]

  That’s not a good thing.

  Pre-cooking the fries in a water bath the way McDonald’s does accomplishes two goals. First, it rinses off excess simple sugars, helping the fries attain a light gold color, instead of a deep dark brown. Secondly, it activates an enzyme called pectin methylesterase (PME). According to an article in the Journal of Agricultural and Food Chemistry, PME induces calcium and magnesium to act as a sort of buttress for pectin. They strengthen the pectin’s hold on the potato cell’s walls, which helps the potatoes stay firmer and more intact when cooked to a higher temperature. That’s why the surface of a McDonald’s fry looks the way it does: rather than blistering into large bubbles like a traditional double-fried french fry does, the reinforced walls form the super-tiny bubbles that give them their extra crunch.

  Now, like most enzymes, PME is only active within a certain temperature range, acting faster and faster as the temperature gets higher until, like a switch, it shuts off completely once it reaches a certain level. 170°F is just under that cutoff point.

  My objective just became much clearer: in order to get my fries ultra crisp, I’d need to find a way to strengthen their pectin before allowing their starch granules to burst.

  Bringing Home the Gold

  The most obvious way to do this is just to copy McDonald’s exactly: cook the potatoes in a precisely maintained 170°F water bath for 15 minutes. I tried it using my Sous-Vide Supreme, followed by a fry at 360°F for 50 seconds, and a second fry at 375°F for 3 ½ minutes. It worked like a charm. The fries tasted nearly identical to those that come from McDonald’s. Of course, now two new questions entered my head: What about for those poor souls who don’t have a temperature-controlled water bath? And more importantly, now that I’ve got the fries down, could I make them even better? I mean, they taste fantastic now, but we all know that McDonald’s fries get soggy pretty darn fast. If these fries were really going to be perfect, I’d have to address that issue.

  To solve the first problem, my initial thought was to start the potatoes in cold water, and slowly bring it up to a simmer. My hope was that by doing this, they’d spend enough time under the 170°F cutoff point to improve their structure adequately. No dice. The potatoes were certainly better than ones dunked straight into the fryer, but they didn’t come close to the originals. Next I tried adding a measured amount of boiling water to a pot containing the cut potato
es. I calculated exactly how much water I’d need in order for it to equilibrate to 170°F. It worked a little better, but the water temperature dropped off too quickly for it to be effective. Was I gonna have to break out the beer cooler for this one? There had to be another way.

  That’s when I thought—perhaps there is another way to strengthen pectin without having to rely on some fickle enzyme (I’ve never liked enzymes anyway), and it struck me: apple pie.

  What’s this got to do with french fries? Well everyone who’s ever baked an apple pie knows that different apples cook differently. Some retain their shape, while others turn to mush. The difference largely has to do with their acidity. Thus super tart apples like Granny Smith will stay fully intact, while sweeter apples like a Macoun will almost completely dissolve. Just like a potato, apple cells are held together by pectin. Moral of the story: acid slows the breakdown of pectin.

  What if rather than trying to fiddle with temperature, I just relied on the use of acid to help the potatoes keep their structure?

  I tried bringing two pots of cut potatoes to a boil side by side, the first with plain water, and the second with water spiked with vinegar at a ratio of one tablespoon per quart. [ . . . ] The fries boiled in plain water disintegrated, making them nearly impossible to pick up. When I added them to the hot oil, they broke apart even further. On the other hand, those boiled in the vinegared water remained perfectly intact, even after boiling for a full ten minutes. When fried, they had fabulously crisp crusts with tiny, bubbly, blistered surfaces that stayed crisp even when they were completely cool. As for the flavor, if I tasted really hard, I could pick up a faint vinegary undertone, though I wouldn’t have if I didn’t know it was there. Even knowing it was there, it wasn’t unpleasant at all. After all, I’m used to putting my fries in ketchup or mayo, both of which contain plenty of acid. [ . . .]
