1 small red onion, chopped
6 large or 8 small tomatillos
2 small or 1 large poblano peppers
juice of 1/2 lime
1/4 teaspoon sea salt
1/2 cup packed chopped cilantro
1 packet nondairy culture starter powder
Preheat oven to 350 degrees. Remove husks from tomatillos and put chopped onion, whole tomatillos, and whole peppers on a cookie sheet or in a shallow pan. Bake 15 minutes.
Remove stems from peppers and seed if desired. Put baked ingredients in a blender or food processor and add lime juice and salt. Pulse a few times to blend (but leave chunky). Allow to cool to room temperature, then stir in culture starter and cilantro.
Put salsa in a mason jar, leaving an inch between the top of the salsa and the top of the jar. Liquid should cover the vegetables.
Put lid on jar and leave at room temperature to culture for 2 days. Then refrigerate. Use within one month.
