The all-crust hamburgerApr 01 2014

Kenji Lopez-Alt and the folks at the Harlem Shake restaurant have invented a burger that's all delicious brown crust.

See, by placing a ball of meat on a hot, un-oiled griddle and smashing it down firmly into a flat, thin disk, you greatly increase the contact points between the meat and the griddle, which in turn increases the Maillard reaction. That's the series of chemical reactions that creates the rich brown crust that makes our steaks and burgers taste so freaking good. Maximum crust = maximum flavor = maximum craving.

I've already discussed the basic ins and outs of smashed burgers in the past, but after writing that article, I found myself wondering, what if I were to take this to the extreme? Is there a way I can pack even more flavor into a burger?

Spoiler alert: the answer is a big fat (or should I say short smashed?) yes.

How to make the perfect chocolate chip cookieDec 20 2013

At Serious Eats, Kenji Lopez-Alt turned 32 pounds of flour and other ingredients into more than 1500 cookies and in the process discovered how to make the perfect chocolate chip cookie.

You see, I've never been able to get a chocolate chip cookie exactly the way I like. I'm talking chocolate cookies that are barely crisp around the edges with a buttery, toffee-like crunch that transitions into a chewy, moist center that bends like caramel, rich with butter and big pockets of melted chocolate. Cookies with crackly, craggy tops and the complex aroma of butterscotch. And of course, that elusive perfect balance between sweet and salty.

Some have come close, but none have quite hit the mark. And the bigger problem? I was never sure what to change in order to get what I want. Cookies are fickle and the advice out there is conflicting. Does more sugar make for crisper cookies? What about brown versus white? Does it matter how I incorporate the chocolate chips or whether the flour is blended in or folded? How about the butter: cold, warm, or melted?

So many questions to ask and answers to explore! I made it my goal to test each and every element from ingredients to cooking process, leaving no chocolate chip unturned in my quest for the best. 32 pounds of flour, over 100 individual tests, and 1,536 cookies later, I had my answers.

Dang, this is like The Power Broker for baked goods, a cookie magnum opus.

Update: Back in 2007, my wife took a different approach to making the perfect chocolate chip cookie: she averaged the ingredients from 12 of the best cookie recipes she could find. The averaged recipe reads, in part:

2.04 cups all-purpose flour
0.79 tsp. salt
0.79 tsp. baking soda

0.805 stick unsalted butter, softened to room temperature
0.2737 stick unsalted butter, cold
0.5313 stick unsalted butter, melted

Seven myths about cooking steakJun 12 2013

For the Food Lab, Kenji Lopez-Alt debunks some old wives' tales related to cooking steak.

Myth #2: "Sear your meat over high heat to lock in juices."

The Theory: Searing the surface of a cut piece of meat will precipitate the formation of an impenetrable barrier, allowing your meat to retain more juices as it cooks.

The Reality: Searing produces no such barrier-liquid can still pass freely in and out of the surface of a seared steak. To prove this, I cooked two steaks to the exact same internal temperature (130^0F). One steak I seared first over hot coals and finished over the cooler side of the grill. The second steak I started on the cooler side, let it come to about ten degrees below its final target temperature, then finished it by giving it a sear over the hot side of a grill. If there is any truth to the searing story, then the steak that was seared first should retain more moisture.

What I found is actually the exact opposite: the steak that is cooked gently first and finished with a sear will not only develop a deeper, darker crust (due to slightly drier outer layers-see Myth #1), but it also cooks more evenly from center to edge, thus limiting the amount of overcooked meat and producing a finished product that is juicier and more flavorful.

If you're serious about home-cooked steak, the "Further Reading" section at the bottom of this piece is your new best friend.

Serious Eats cookbook out soonApr 15 2011

But it's more than a cookbook...here's the description from Facebook (the "me" is Kenji Lopez-Alt, SE's resident mad scientist):

It's coming out November, has 50 recipes from me, and whole bunch of awesome recommendations for the best food around the country.

The title is Serious Eats: A Comprehensive Guide to Making and Eating Delicious Food Wherever You Are and it's available for preorder on Amazon.

In-N-Out super secret menu revealedMar 04 2011

Kenji from Serious Eats went to In-N-Out, found a willing employee accomplice ("Awesome! I've been waiting for this day ever since I started working here!"), and proceeded to order one of everything off of the menu, the well-known secret menu, and the not-so-well-known super secret menu.

That should make you feel better about yourself when you tuck into the meat and cheese fest known as the Flying Dutchman -- the ultimate Atkins-friendly menu item. Two slices of cheese melted between two burger patties. No rabbit food, no wimpy buns, just pure protein and fat. Want to kick up the manliness by yet another factor? Ask for a Flying Dutchman Animal Style and they'll add a scoop of diced onions to the cheese. Pickles and spread will come on the side, so you'll have to add them yourself. "I wish we could add the spread and pickles for you, but it's just too messy for the cooks," explained an apologetic Thomas. The result definitely wins the award for messiest menu item of all time.

Fast caramelized onionsJan 24 2011

Over at Serious Eats, Kenji Lopez-Alt shows how you can cut your onion caramelization time from 45 minutes to about 15 or 20 minutes.

Before we can figure out how to improve our end results, it's important to understand exactly what's going on when an onion browns. First, the onions begin by sweating. As they slowly heat up, moisture from their interior (they are roughly 75% water by weight) begins to evaporate, forcing its way out of the onion's cells, and causing them to rupture in the process. This breakdown of the cells is what causes onions to soften during the initial stages of cooking.

Why foie gras is not unethicalDec 16 2010

Over at Serious Eats, Kenji Lopez-Alt has a long piece about a visit he took to a foie gras producer in New York's Hudson Valley and what he learned about the ethics of foie gras production.

Even if you haven't eaten foie, pretty much everyone is familiar with the abhorrent images of mistreated ducks peddled by PETA and sites like nofoiegras.org, and indeed they are truly disturbing. Ducks crammed into wire cages just big enough to stand in with their filth-encrusted heads sticking out a hole in the front. Their feathers are scraggly and wiry (if present at all), there's often blood coming out of their nostrils, and their faces and feathers are caked with vomit and corn meal. A duck drinks scummy water out of a communal trough running in front of it while just upstream one of its less fortuitous bunkmates sits dead with its head lolling sideways, half submerged in the cloudy green water.

I've no doubt that farms like this exist in the world, and it is a terrible, atrocious tragedy. If this is how all foie-or even all meat-is produced, I'd become a vegetarian today. But video or photographic footage of one badly managed farm or even a thousand badly managed farms does not prove that the production of foie gras, as a practice, is necessarily harmful to the health or mental well-being of a duck. Foie gras production should be judged not by the worst farms, but by the best, because those are the ones that I'm going to choose to buy my foie from if at all.

So the real question is: is the production of foie gras torturous under even the best of conditions?

Those on one side would answer yes. How could force feeding an animal ever be considered anything but torture? On the other hand are those who claim that American foie farms are positively idyllic with ducks waddling around spacious pens, even queuing up for their gavage, that for a duck, none of the things we consider uncomfortable stress them out in the least. But who's right?

The perfect poached eggOct 28 2010

Kenji Lopez-Alt learns the secret to the perfectly poached eggs at Maialino. They basically use the Momofuku slow-poach technique and then finish in a simmering water bath.

Food myths debunkedOct 12 2010

Kenji Lopez-Alt busts six stubborn food myths.

4. Searing "Locks In" Juices. This is the oldest one in the book, and still gets repeated-by many highly respected cookbook authors and chefs!-to this day. It's been conclusively proven false many times, including in our own post on How to Cook a Perfect Prime Rib, where we found that when roasting a standing roast, it in fact lost 1.68% more juice if it was seared before roasting rather than after! The same is true for pork roasts, steaks, hamburgers, chicken cutlets, you name it.

How to: perfect Neapolitan pizza at homeSep 16 2010

Over at Serious Eats, Kenji Lopez-Alt assures us that while you can't make restaurant-quality Neapolitan pizza at home, you can come damn close. Best thing is, his technique doesn't involve lining your oven with bricks and is actually as easy as making regular pizza at home.

After cooking for around a minute and a half, the bottom crust achieved the perfect degree of char-even better than what I was getting on the stone. Interestingly enough, the pan was actually cooler than the stone I was using, maxing out at around 450 degrees. So how does a 450 degree pan brown better and faster than a 550 degree stone? It's a matter of heat capacity and density.

The heat capacity of a material is directly related to the amount of energy that a given mass of material holds at a given temperature. Even though stone has almost twice the heat capacity than steel (.2 kcal/kg C vs. .1 kcal/kg C), it loses in two ways: it is far less dense than steel, and it has a much lower rate of heat conduction than steel. The pizza cooking in a skillet is not just getting energy from the pan-it's getting energy from the burner below the pan as it gets rapidly conducted through the metal.

It's a clear demonstration of how when cooking foods, what matters it the amount of energy transferred, not just the temperature you cook at. The two are often directly related, but not always.

I have said it before but will repeat: I love Kenji's nerdiness about the science combined with the ability to come up with the solution that's easiest for non-nerds to appreciate and implement. It is a rare and wonderful thing to observe.

Make your own In-N-Out Burger at homeJul 23 2010

Today in the excellent Food Lab series, Kenji Lopez-Alt reverse engineers the In-N-Out burger.

According to the In-N-Out nutrition guideline, replacing the Spread with ketchup results in a decrease of 80 calories per sandwich. I know that ketchup has about 15 calories per tablespoon, so If we estimate that an average sandwich has about 2 tablespoons of sauce on it (that's the amount that's inside a single packet), then we can calculate that the Spread has got about 55 calories per tablespoon (110 calories in two tablespoons of Spread minus 30 calories in 2 tablespoons of ketchup = 80 calories difference in the sandwich). With me so far?

It just so happens that relish has about the same caloric density as ketchup (15 calories per tablespoon), and that mayonnaise has a caloric density of 80 calories per tablespoon. Using all of this information and a bit of 7th grade algebra, I was able to quickly calculate that the composition of the Spread is roughly 62 percent mayo, and 38 percent ketchup/relish blend.

Here's the recipe to make your own at home. Pairs well with make-at-home McDonald's french fries. See also make-at-home Shake Shack burger.

How to make McDonald's fries at homeJun 03 2010

It involves finagling some uncooked frozen fries from a local McDonald's under the ruse of a scavenger hunt. Kenji Lopez-Alt explains.

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.

Here's the full recipe/instructions. BTW, Kenji's series of posts on Serious Eats is one of the best things going on the web right now (you might remember his sous-vide in a beer cooler hack). Passionate down-to-earth writing about cooking and food backed by some serious skills and scientific knowledge...it's really fun to read.
