Tempering (spices)

Tempering is a cooking technique used in India, Bangladesh, Nepal, Pakistan, and Sri Lanka in which whole spices (and sometimes also other ingredients such as dried chillies, minced ginger root or sugar) are cooked briefly in oil or ghee to liberate essential oils from cells and thus enhance their flavours, before being poured, together with the oil, into a dish.^[1] Tempering is also practiced by dry-roasting whole spices in a pan before grinding the spices. Tempering is typically done at the beginning of cooking, before adding the other ingredients for a curry or similar dish, or it may be added to a dish at the end of cooking, just before serving (as with a dal, sambar or stew).^[2]
