Chicken Curry Sauce

This is a Nigerian take on a curry sauce: chicken breast marinated in ginger, garlic and all purpose seasoning, cooked with carrots and bell peppers, and thickened with a cornstarch slurry rather than reduced or enriched with cream. Two things mark it as Nigerian rather than South Asian. The first is yaji, the suya spice built on ground peanuts, paprika, cayenne, ginger and garlic, which goes in alongside the curry powder and gives an aromatic depth no Indian curry would have. The second is the cornstarch slurry, which is how a great many Nigerian sauces are thickened, giving a glossy sauce that clings rather than a reduced one. The vegetables are meant to keep their bite. Carrots and bell peppers go in after the onion and are cooked only until slightly tender, which is characteristic of Nigerian party cooking, where texture and colour matter as much as flavour. The heat is moderate and adjustable through the scotch bonnet. Because yaji contains ground peanuts, this dish carries a peanut allergen despite nothing in its name suggesting one.
