This is based on a recipe from Saveur magazine, but they didn't use as many peppers.
Super Secret Recipe
habanero peppers -2
serrano peppers -2
cilantro several sprigs, diced
onion 1/2 medium white
garlic several cloves
tomatoes 1 large can, diced or peeled
1) Peppers: remove the stems, slice, and remove the seeds if you desire a flavorful but less spicy salsa
2) put the tomatoes, garlic, and peppers in a pot and simmering at a low boil for 20 minutes
3) after simmering, mix everything together in a food processor or similar. Do less mixing for a chunkier salsa but a finer mix will better spread all the flavors/spice.
