How to Make Suya Spice at Home (Nigerian Yaji)

Yaji is the spice blend that makes suya suya. Ground roasted groundnuts form its base, and that is what separates it from every other dry rub in the world: a spice mixture built on a nut rather than on seeds and chillies alone. Ginger, garlic, onion and paprika go in around it, with cayenne carrying the heat. It belongs to the Hausa of Northern Nigeria, and the recipes are held closely. Every suya vendor guards a proprietary arrangement of spices, and the specific balance is treated as commercial property rather than shared knowledge, which is why no two suya taste quite the same and why the exact composition is genuinely difficult to pin down. What is consistent is the groundnut, the aromatics and the heat. Its use extends well past the meat it is named for. Yaji is a marinade, a dry rub applied before grilling, and a finishing powder scattered over meat as it comes off the fire, and Nigerians use it on roasted vegetables, on fish, on chips, on plantain and on nuts. It is sold ready made at Nigerian grocers, and having a jar of it in the house is the single fastest route to making Nigerian food taste like itself.
