Suya Spice (Yaji)
What it is
A complex, savory, peanut-based dry spice rub from West Africa — especially northern Nigeria, Niger, and across the Hausa-speaking Sahel — used to season suya, the famous spiced grilled-meat skewers sold by roadside mai suya vendors. Also called yaji. Reddish-brown, coarse-to-fine, and instantly recognizable by its groundnut (peanut) base.
How it's made
The defining ingredient is kuli-kuli powder — ground, defatted roasted peanuts (the peanuts are pounded, the oil pressed out, fried into kuli-kuli cakes, then ground). To this are added ground ginger, cayenne/chili, paprika, garlic powder, onion powder, and often a little bouillon/seasoning salt, with regional additions like clove, grains of selim (uda), or other Sahelian spices. The defatted peanut powder is essential: it must be low-oil so it clings as a dry rub rather than turning into peanut butter on the heat.
Flavor profile
Nutty, smoky, savory, and hot — deep roasted-peanut richness, warm ginger, building cayenne heat, and umami from the bouillon and onion-garlic. The peanut base gives a rounded, almost meaty depth unusual among dry rubs.
Culinary uses
Suya skewers above all — thin slices of beef (especially), ram, chicken, or offal are coated in yaji, grilled over wood/charcoal, then dusted with more raw yaji and served with sliced onions, tomatoes, and cabbage. Also used on grilled fish, plantain, and as a general West African barbecue seasoning. How to use: rub onto meat before grilling, then crucially re-dust with fresh yaji after cooking — the post-grill raw coating delivers the signature peanut-and-pepper punch. Some of the rub is held back specifically for this finishing dust.
Regional variations
Recipes vary across the Hausa Sahel and the wider West African diaspora; heat levels, the presence of grains of selim or clove, and the peanut-to-spice ratio all shift by vendor. Tsire (below) is the closely related Hausa peanut-spice powder for the classic tsire-style suya — the terms overlap heavily, with tsire often referring to the skewered preparation and its powder.
Cultural & historical context
Suya is a cornerstone of Hausa culinary culture and one of West Africa's great street foods, spread across Nigeria and beyond by Hausa traders and migrants. The mai suya (suya seller) and his smoky roadside grill are an iconic sight across northern Nigeria and the cities of the south. Yaji's peanut base reflects the groundnut's centrality to Sahelian agriculture and cuisine. Suya has become a pan-Nigerian and diaspora favorite, a unifying food across ethnic lines.
Sourcing notes Commercial yaji is sold in West African groceries and increasingly online, but freshness matters — the peanut powder can go stale or rancid, so small, fresh batches are best. Homemade is excellent if you can source or make kuli-kuli (defatted peanut powder); using regular peanut flour with the oil removed is the key technical step.
