This clarified butter sauce, traditionally used with seafood, features three types of dried chilies, each chosen for their specific flavors. Chile de arbol is a bright red, extremely hot pepper that adds color and spice. Chipotle pepper adds smoke and the ancho chili is milder in heat and deeper in color. The chilies are gently fried in butter as it is clarified, then removed before serving.
The clarification process—cooking butter over low heat so the milk solids cook out—makes a perfectly clear dipping sauce with nutty undertones. This sauce is a spicy one, so it’s ideal for heartier fish rather than a delicate sole or flounder and is a delicious dipping sauce for steamed lobster, crab or clams.
