Suya Spice Rub (Yaji — Groundnut to Spice)

2

Defatted groundnut (peanut) powder — Dry-roasted peanuts ground to powder, then pressed or blotted to reduce fat content; provides structural bulk and caramelizable proteins

0.5

Ground dried red pepper (tatashe or cayenne) — Heat and color; tatashe gives mild smoky sweetness, cayenne amplifies heat — blend to preference

0.2

Ground ginger (dry) — Aromatic warmth essential to the yaji profile

0.1

Garlic powder

0.15

Kuli-kuli powder or additional groundnut meal — Optional; dried groundnut cake intensifies nuttiness

0.1

Salt

0.05

Maggi or bouillon powder — Widely used in West African kitchens; adds glutamate depth — traditional but optional in home recipes

Dry-roast raw groundnuts in a pan over medium heat until golden brown and fragrant, stirring constantly (10–15 minutes). Remove papery skins by rubbing in a cloth. Grind to a coarse powder — not butter. Press briefly through a fine cloth or use defatted groundnut flour to reduce oil content, which would cause the rub to clump and burn unevenly. Combine groundnut powder with all spice components and mix well. Slice beef (sirloin or topside) across the grain into strips approximately 5 mm thick. Thread onto flat metal skewers. Brush meat lightly with neutral oil, coat generously with yaji blend pressing into the surface, and allow to rest 30 minutes minimum. Grill over high charcoal heat, rotating often, and dust with additional dry yaji during the final 2 minutes to build a second layer of crust.

• Use defatted groundnut flour whenever possible — excess fat in the powder causes flare-ups on charcoal and produces an oily, under-crusted exterior rather than a clean, charred crust.
• Flat metal skewers (not round bamboo) prevent the meat from spinning during grilling, ensuring even char on both broad faces.
• Authentic suya uses very high, direct charcoal heat — the rapid high-heat char before the center overcooks is what makes the texture distinct; a gas grill set to maximum is a reasonable substitute.
• Serve with raw sliced onion, tomato, and additional dry yaji dusted tableside — this condiment presentation is as canonical as the rub itself.
• Rest the skewers on the side of the fire rather than directly over coals for the last 3–4 minutes to allow carryover heat to finish the center without burning the crust further.

• Chicken suya

  Same yaji ratio; chicken breast or thigh strips; higher oil-brush before rub application to compensate for lower fat content

• Fish suya

  Reduce application rate to 10% meat weight; add ground crayfish at 5% of rub for the seafood-specific version popular in coastal states

• Kilishi

  Dried meat variant: yaji applied to thin dried beef sheets and sun-dried until shelf-stable; groundnut ratio shifts toward 3:1 to prevent oxidative rancidity during drying

• Asun-style pepper-heavy yaji

  Yoruba variation with doubled pepper fraction and fresh chopped green scotch bonnet added post-cook

• Diaspora yaji without Maggi

  Replace bouillon with nutritional yeast + smoked paprika for similar glutamate depth without additives

• Dry Rub Ratio for BBQ (Salt to Sugar to Spice)

  Western analog: spice-to-meat weight control for grilled/smoked protein

• Shawarma Spice Rub

  Middle Eastern warm-spice rub applied by similar weight-to-meat proportion logic

• Tandoori Marinade Ratio

  Another region's pre-grill protein treatment; yogurt binds spice in place of groundnut powder
