Kachumber Salad — Raw Vegetable Relish (कचुंबर)

Pan-South Asian — present in every regional tradition from Punjab to Tamil Nadu; the Persian influence (kakh = cucumber + amber = raw) is linguistically traceable

Kachumber is the sub-continental raw vegetable relish — a simple preparation of diced tomato, cucumber, and onion with coriander, green chilli, and lime juice that appears alongside almost every significant Indian, Pakistani, and Parsi meal. It is not a salad in the Western sense — the pieces are small (5mm dice), the lime juice is generous enough to partially macerate the vegetables, and the salt is applied just before service to prevent excess water release. Kachumber's function is thermal and textural: it provides cold, acidic, crunchy contrast to the hot, spiced, fatty dishes it accompanies.

Served alongside biryanis, kebabs, dals, and curries. The cold-acid contrast is the functional role.
