"This version of a classic Spanish salsa combines a slow-cooked tomato sauce including zest of lemon, cilantro, ripe mangos, and lemon juice. For hot salsa use 3 habanero peppers. For 'fuego' (fire) use 3 Habanero and 3 Jamaican peppers. Goes great with chips, chicken, rice, or beans."
Bring a large pot of water to a boil; add 6 tomatoes. Boil tomatoes until skin starts to peel, 1 to 2 minutes. Remove tomatoes with a slotted spoon and place in a bowl of ice water until cool enough to handle, about 5 minutes. Peel skin, cut in half, and remove seeds. Blend seeded tomatoes in a blender until smooth.
