An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Wash the cauliflower and carrots and dry them completely; any moisture spoils the pickle.
Toss the vegetables with half the salt and set aside for 2 hours, then drain the released water.
Coarsely grind the mustard, fennel, fenugreek, and nigella seeds, then mix with the red chili powder and remaining salt.
Heat the mustard oil until it just smokes and let it cool; toss the vegetables with the ground achari masala and oil in a sterilized jar.
Leave the jar in the sun or a warm spot for 3-4 days, shaking it daily.
Serve the tangy, spiced pickle in small portions with roti, paratha, or dal.
