Recipe for Guacamole con Tomate Verde and Tomate Riojas adapted from Diana Kennedy:
3 tbsp. finely chopped white onion
4 chiles serranos, finely chopped
2 rounded tablespoons, finely chopped cilantro
Scant ½ tsp. sea salt
6 oz or 8 medium tomatillos (broiled—method follows)
3 large Avacados
1 cup finely chopped unpeeled tomato
For the topping:
2 tbsp. finely chopped white onion
1 heaping tbsp. finely chopped cilantro
1. First, broil the tomatillos. Remove the papery husk and rinse the tomatillos. Don’t attempt to skin them. Put the tomatillos into a heavy cast iron pan. Put them under the broiler and cook them until they are fairly soft and the skin is lightly charred (About 5 minutes) When you grind them, include the skin.
2. In the molcajete, grind the onion, chiles, cilantro and salt to a paste. Add the broiled tomate verde, a few at a time, mashing and grinding the skin as much as possible.
3. Cut the avocados in half and remove the pits but do not discard. Scoop out the flesh with a wooden spoon and mash roughly into the base mixture, turning it over from the bottom so that the seasoning is well distributed. Put the pits back into the mixture.
4. Wait until the last minute to add the diced tomato, mixing it in.
5. Sprinkle the top with onion and cilantro and serve immediately.
