Coquitos is a Christmas tradition in Cuba and Puerto Rico much like eggnog here in the USA and elsewhere. It is like a sweet wine. It is served on the night of Noche Buena (good night) before eating Lechon Asado (roast pig), Arroz Congri(white rice and black beans - made together), Yuca con Mojo (yucca or cassava with garlic sauce), Maduros Fritos(fried ripe plantains) - leave it to the Cubans to serve three carbohydrates at one meal! Anyway, along with the meal they serve Ensalada Mixta (mixed green salad with tomatoes & radishes) and for dessert Bunuelos(fried dough pieces with syrupy syrup) and then they all go to La Misa del Gallo(mass of the rooster - Midnight Mass). Found on . that is the recipe.
