An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Wash the lemons and pat them completely dry, then cut each into 8 wedges and remove the seeds.
Dry-roast the fenugreek seeds until fragrant, cool, and grind to a fine powder.
Toss the lemon wedges with the salt, mustard powder, fenugreek powder, nigella seeds, turmeric, and red chili powder.
Pack the mixture tightly into a sterilized, dry glass jar and pour the mustard oil on top.
Keep the jar in the sun for 7-10 days, shaking it daily, until the peels soften and the flavours meld.
Serve in small portions with parathas, dal, rice, or curd rice.
