Suya spice, also called yaji, is a fiery blend of ground chiles, ginger, garlic and onion powders. It also usually contains fermented locust beans or bouillon cubes, and has one other ingredient that really sets it apart: ground peanuts. Traditionally the peanuts are ground into butter and then put through a process to extract excess oil, after which the nut paste is fried or roasted into a brittle mass known as kuli kuli. The kuli kuli is then ground again and mixed with the spices mentioned above for an earthy, nutty, deeply savoury and vibrant mix of flavours.
