Step 1

Puree all the jalapeño sauce ingredients in a food processor until your desired consistency is reached. I sometimes add a little more oil or water at the end to make the sauce less gloppy and more drizzle-able.

Step 2

Pat the fish dry with paper towels and cut into 2-3 inch pieces. Put 1/2 cup flour in a shallow bowl and set aside. In a separate bowl, whisk 1/2 cup flour, cornmeal, cornstarch, chili powder, baking powder, and salt. Add the beer and the beaten egg; stir until combined to form the batter.

Step 3

Pour enough oil in a frying pan so that the fish will be partially submerged while frying. Heat the oil until a drip of water sizzles across the top. Dip each piece of fish in the plain flour, then the batter, then transfer to the hot oil. Fry on each side for 3-5 minutes or until golden brown and crispy. Remove from the frying pan and transfer to a plate lined with paper towels to drain excess oil. Sprinkle with salt while still hot; let cool slightly.

Step 4

Arrange your tacos with a few pieces of fish, cilantro, Cotija cheese, and jalapeño sauce. Yummy!
