From the Nahuatl meaning "concoction," mole is a rich, dark, reddish-brown sauce usually served with poultry. There are many variations of this spicy Mexican specialty, usually depending on what's in the cook's kitchen. Generally, mole is a smooth, cooked blend of onion, garlic, several varieties of chiles, ground seeds (such as sesame seeds or pumpkin seedsknown as pepitas) and a small amount of mexican chocolate, its best-known ingredient. (Some Americanized mole recipes use bitter chocolate.) The chocolate contributes richness to the sauce without adding overt sweetness.
