Forget what your kindergarten teacher told: It's not what's inside that counts. At least not when it comes to tacos.

According to Alex Stupak, who just wrote a book on the subject, the difference between a great taco and a crappy one comes down to the tortilla.

Stupak defines a taco as "a tortilla with a product on it that you want to eat and the appropriate dressing or accoutrement." The tortilla, be it flour or corn, is the taco's foundation, and its quality is essential. Just as some Japanese sushi chefs argue that sushi is 90% about the rice, Stupak claims that tacos are about the tortillas. 

And that explains why the cover of his book on tacos is a strikingly bare tortilla, nothing to cover it up in sight. 

My attempt to recreate the cover at home

Don't even ask: No, you cannot subsitute store-bought tortillas with a clear conscience: "There is absolutely no substitute for a fresh, homemade tortilla, and suggesting any kind of store-bought alternatives would keep me up at night," Stupak writes. 

At his three taco-serving Empellón restaurants in Manhattan, tortillas are made of fresh masa, which is itself made from ground nixtamal. That's a word you might never have heard before—and one I didn't even attempt to pronounce until last week.

Nixtamal is produced when dried, whole kernel field corn—not your eat-on-the-cob sweet corn, this is the majority of corn grown on the planet and is used in everything from animal feed to toothpaste—is made edible. The kernels are treated with an alkaline solution of water and calcium oxide (called "pickling lime"), which takes at least 12 hours, and then ground into masa.

If this all sounds very complicated, it might come as a relief to know that you can't do this at home (Stupak says so!). Even if you make the nixtamal (and yes, there is a recipe in the book), there's no reliable piece of home kitchen equipment that will get the grinding job done. The only way they do it at Empellón (and at Hot Bread Kitchen, where they also make tortillas starting with real corn) is with an industrial corn grinder.

If you want to start with fresh masa, you'll have to tap into the resources of a nearby tortilla factory (and this will be in easier in San Diego or Chicago than, say, Fairbanks).

So what to do if you really want to obey Stupak's laws but you don't want to track down fresh masa? Use masa harina, an instant flour made from dehydrated masa. Masa harina is to masa as Folger's coffee is to the real stuff, says Stupak, but it still makes a tortilla better than the packaged options.

Still, I was skeptical that I could do this myself. Though Stupak made it seem easy to make corn tortillas when I visited him at his restaurant, could I really do it myself at home? I borrowed a taco press from Kenzi, mixed 1 1/2 cups masa harina with 1 cup of water, and kneaded to rehydrate.

The first challenge was getting the mixture to be the right consistency. You want the masa to be malleable and moist, but not overly wet. The dry dough cracked and crumbled under the press, whereas the wet mixture stuck to the plastic and the pan.

Once I got the moisture-level right, the next obstacle was controlling the heat of the skillets (yes, skillets multiple). For Stupak's recipe, you cook the tortilla first in a medium-high skillet (15 seconds on each side) and then you move it to a scorching hot skillet and cook it for 30 seconds, flip for 10 seconds, and then flip for a final 10 seconds.

If you've done it right, the tortilla will puff up dramatically once it moves to the hotter skillet. You will cheer and dance and attempt to take a video.

Once I had cooked a few tortillas, I figured out a system with my roommate: As soon as I had moved the tortilla to the hotter pan, she would press the dough and lay it down into the cooler pan. 

We got into a groove until the magic stopped. With almost no warning signs, our dough stopped cooperating, no matter how much masa harina or water I added to try to achieve homeostasis. It cracked and stuck to the plastic and generally frustrated us. So we stopped and ate the earlier models instead.

And how did they taste? Their texture was definitely superior to any store-bought corn tortilla I've tried. But the flavor wasn't, walking the line between bland and bitter. My hypothesis is that the masa harina was stale. Since it's the only ingredient in the recipe, its quality is imperative.  

I would, however, seek out some new masa harina and make these again. It wasn't difficult and it brought me the satisfication that only DIY projects can. And only once I've mastered the tortilla will I move on to the stuff inside—I have a feeling that will be a while. 

Why did my tortillas taste a little off? Share your advice in the comments.
