Choose a substitute based on your recipe needs: pickled cherry peppers for closest match, piquillo for cooking, or raw mini bell peppers for crunch without heat.
If needed, prepare the substitute by slicing, quick-pickling, or drizzling with honey (for jalapeño + honey).
Apply the suggested 1:1 ratio or specified amounts, adjusting sweetness, tang, or heat as preferred.
In cooked dishes, warm or simmer substitutes like piquillo peppers to integrate flavors; for raw uses, use fresh or pickled substitutes as is.
Taste your dish and adjust with extras like vinegar or honey to replicate the sweet-tart-heat balance if necessary.
