At long last, tomatillos have returned to the farmers' market, and now I can dive back into Mexican cooking again. In California, the tomatillo season is similar to tomato season, running from July through October. Tomatillos are slightly sour, sharp and fruity, a combination which is delicious counterpoint to the mellow, round flavors of a corn tortilla and the creaminess of a melting cheese like Monterey Jack. Roasting is an especially good treatment for these little green gems, as it draws out some of the natural sugars, then carmelizes them and adds a hint of smokiness.
I first used all of the tomatillos to make a thick, slightly chunky tomatillo salsa (recipe below). Then, later in the week, I took the remaining salsa, and converted it into a thin, smooth sauce to use in enchiladas verdes, the process for which I will describe below.
I used the salsa as the finishing touch on a plate of enfrijoladas (tortillas coated with pureed black beans) that were topped with roasted nopales (cactus paddles), zucchini, and grated melting cheese. A recipe from Rick Bayless' TV show served as my guide. Like enchiladas, the dish starts with a sauce---pureed black beans in this case. Then, one-by-one you set a hot tortilla onto the hot pureed beans, gently flip it over to complete the coating, put some grated cheese in one quadrant of the tortilla, fold it in half, and then fold once more to make a quarter circle. The image below shows the "tortilla origami."
A few days later, I took the remaining salsa and converted it into an enchilada sauce using the following procedure to adds complexity (pouring the sauce into hot oil lets the flavor forming Maillard reaction occur, for example):
- Heat a tablespoon or two of vegetable oil in a deep, heavy saucepan over medium-high heat
- When the oil is hot, carefully pour in the salsa (it might splatter). When it is safe to do so (a few seconds later), stir the mixture thoroughly.
- Reduce the heat to medium, and cook the salsa, stirring frequently, until it thickens to the consistency of tomato paste (about 10 minutes).
- Pour in some water or broth, enough to make the final mixture about as thick as tomato sauce. Puree the mixture using an immersion blender or countertop blender (being careful with the hot liquid in the blender).
- Keep the mixture warm over low heat until the tortillas are ready.
- Add salt to taste.
Roasted Tomatillo Salsa (Salsa Verde)
About 20 Tomatillos
1 to 4 green chiles (I prefer serrano)
3 to 9 cloves of garlic, unpeeled
1/4 to 3/4 bunch cilantro, chopped
1/4 to 1/2 white onion, diced
1) Turn on the broiler.
2) Place unpeeled garlic cloves and serrano chiles in a dry skillet over medium
heat. Cook, turning them occasionally, until the garlic is soft and the chiles are blackened, about 10-15 minutes. After they cool, peel the garlic and remove some of the seeds and membrane from the chiles (the membrane contains the chile's heat).
3) Peel husks from tomatillos, then wash them thoroughly. Put tomatillos on a baking sheet (use one with sides since there will be juices running)
Place under broiler. Broil until blackened on one side, then turn (they cook at different rates, so you might need to turn them at different times, and remove them as they finish cooking)
4) Put the chopped chiles and garlic into a blender jar. Add a few tomatillos. Blend until smooth. This step allows the garlic and chiles to be fully pureed.
5) Add the rest of the tomatillos, then blend lightly to break them up without making the mixture totally smooth.
6) Put the onion in a colander and put under running water for a few seconds to reduce the bite. Add onion to blender jar. Add salt to taste. Add chopped cilantro and lime juice to taste. Pour into a serving dish and stir to combine.
