Identify how your recipe uses habanero (fresh mince, dried flakes, or liquid heat).
Choose the substitute from the same “heat lane”: closest fruity-heat first, then hotter options (reduce), then emergency options (boost flavor).
Apply the ratio from the table: if using a potentially hotter pepper, start low (e.g., ½) and scale up after tasting.
Match texture: mince fresh peppers finely; rehydrate dried peppers before chopping; stir sauces/flakes in early enough to distribute heat.
Taste at the end and correct: add a little acid (lime/vinegar) or sweetness (honey) only if your dish tastes harsh, not just “not hot enough.”
