Step 1

PreparationPoach the tripe: Poach the tripe in salted water for 3 hours in a large pot, changing the water halfway through. The tripe should be soft and pliable when done. Drain and let tripe cool. Pat dry.

Step 2

Make the herbal tomatillo sauce: Toss the chopped tomatillos, onions, jalapeños, and garlic in 2 tablespoons oil. Broil on a foil- lined baking sheet until vegetables are blackened in spots, 10 to 15 minutes. Purée the blackened vegetables, herbs, fish sauce, lime zest and juice in a blender. Let sauce cool.

Step 3

Pan-fry the tripe: Slice the cooled tripe into 1/4-inch strips. Heat the remaining 1/2 cup of oil in a large nonstick skillet over medium heat. Working in batches, carefully pan-fry the strips of tripe on one side until golden brown. Place tripe on a paper towel–lined plate as you work and sprinkle with salt. After the last batch, drain the pan of all oil and add the pan-fried tripe and the tomatillo sauce. Toss the tripe in the sauce over medium heat until softened and coated.
