Yaji

Also: suya spice, tankora

West African suya spice blend built on roasted ground peanuts, ginger, and paprika, used to coat and finish grilled meat skewers across Nigeria and the Sahel.

/YAH-jee/Hausa language of northern Nigeria and Niger; the tradition of suya and its spice blend originates with the Hausa-Fulani cattle-herding communities of the Sahel and is believed to have traveled south with livestock trade routes during the 19th century.

Definition

Yaji is the proprietary-feeling but widely shared spice mix that transforms suya — the West African street-food skewer tradition — from plain grilled meat into something complex and addictive. Its foundation is roasted and ground peanuts (or groundnut cake, the pressed residue left after extracting groundnut oil), which provide both protein coating and a nutty, slightly gritty texture that clings to the meat. To this base are added ground ginger, paprika or ground dried chiles, garlic powder, onion powder, salt, and often a cube or two of Maggi seasoning ground in. Some versions include ground locust bean (dawadawa), which adds a fermented umami depth. The mix is rubbed onto thin strips of beef, goat, or chicken, which are then threaded onto skewers and grilled over very hot charcoal. The peanut coating chars slightly at the surface while remaining moist beneath, and the skewers are often redipped in dry yaji and served with raw onion and tomato. Across Nigeria, Cameroon, Niger, and Chad, the specific ratios vary by the mallam (suya vendor) and region; in northern Nigeria and among the Hausa and Fulani people who originate the tradition, the blend may be drier and more peppery, while southern Nigerian variations tend toward sweetness and less heat.

In use

“The mallam patted a fresh coat of yaji over the resting beef skewers, the groundnut powder hissing against the residual heat of the grill before the sticks went back over the coals for a final char.”

Notes

Groundnut cake vs. whole peanuts

Traditional yaji uses kuli-kuli (groundnut cake) rather than whole roasted peanuts — the oil has been pressed out, leaving a drier, more concentrated product with a finer grind and a less oily coating. Using whole peanuts produces a good approximation, but the texture on the meat is slightly richer and the coating adheres differently. Many diaspora recipes default to peanut flour, which behaves most like kuli-kuli.

The Maggi factor

Seasoning cubes (Maggi or Knorr, ubiquitous across West Africa) are ground directly into yaji and are not considered a shortcut — they are structural to the flavor. Omitting them for a 'cleaner' spice mix produces a noticeably less characteristic result.
