Ají de Gallina: Creamy Walnut Chicken

Ají de gallina belongs to the Criolla tradition — the cooking of colonial Peru that blended Indigenous ingredients (ají amarillo, native potatoes) with Spanish techniques (bread thickening, cream) and ingredients introduced from Europe and Asia. The bread thickening specifically reflects Spanish/Moorish cooking techniques introduced during the colonial period. The walnut's presence in Peruvian cooking reflects trade routes that brought walnuts from Spain (where they arrived from Persia via the Silk Road).

Ají de gallina — shredded chicken in a creamy ají amarillo sauce thickened with bread and walnuts — is the most beloved Peruvian comfort preparation. Its sauce is technically specific: the bread absorbs the chicken broth, the walnuts provide fat and thickening, and the ají amarillo provides both colour and the characteristic fruity-hot flavour. The bread-and-nut thickening technique produces a sauce with a different texture from starch-thickened or cream-thickened sauces — softer, with a grain that catches and holds the sauce in layers.
