This card covers pungent Capsicum fruits, including chili, cayenne and jalapeño. It does not cover sweet bell pepper. A pepper’s size or colour does not reliably show its heat, and the seeds are not the only source of capsaicin.
The separate cards for bulb onion and garlic explain why either ingredient needs prompt assessment even when it is part of a sauce or seasoning.
