Mango salsa is a lively addition to Baja-style tacos and lighter flavored tacos. Its sweetness contrasts nicely with searing chile heat and it lends a nice peppy feel to tacos dorados and even on top of guacamole. This is one of those salsas that should only be made when mangoes are in season. Otherwise, it will taste very lackluster. Makes 1 1/4 Cups Heat Level: 4
