The dried chile family tree for salsa making
Understanding which dried chile does what is the foundation of salsa making. Here is how I think about the major ones:
Arbol: sharp, forward heat, almost no sweetness. Use for heat. Guajillo: mild, fruity, good color, slight sweetness. Use as a base. Ancho (dried poblano): complex, chocolate undertones, low heat. Use for depth. Mulato: dark chocolate, raisin, deep heat. Use for complexity in mole-style salsas. Pasilla: earthy, tobacco, medium heat. Use with ancho for a complete flavor.
A good cooked salsa is usually a combination: guajillo for color and mild sweetness as the base, arbol for heat, and one depth chile (ancho or pasilla) for complexity.
