Check how your recipe uses wiri wiri pepper: fresh (minced) for bright flavor or dried/powdered for even heat distribution.
Choose the closest match: Scotch bonnet or habanero for fruity heat, bird’s eye for sharper sting, Aleppo for mild fruity warmth, and cayenne/flakes for emergency heat.
Swap using the listed ratio, then taste once the dish is cooked or after the baking batter has fully set (heat concentrates as it cooks).
If your substitute tastes flatter than wiri wiri, add a small brightness boost (a few drops of vinegar or lemon) rather than increasing heat immediately.
For baking, start 25–40% lower than the swap ratio if the pepper is powdered, then increase only if the finished flavor needs more kick.
