Chooran ke Karele

Use the same weight; it is the same vegetable, usually a little milder. Scrape out the seeds and salt if needed.

Use the same weight; it gives no bitterness and more water, so salt and drain it briefly before cooking.

Use the same weight; it is soft and mild, so the dish loses the bitter note entirely.

Use 1:1 by weight. Handles high-heat frying identically and introduces a very subtle, pleasant nuttiness.

Use 1:1 by weight. Yields a much richer, authentic aroma and a glossy, heavier mouthfeel.

Use 1:1 by weight. Heat until smoking, then cool slightly before cooking to temper its intensely pungent, sharp mustard kick.

Use equal weight. Imparts an earthy, slightly bitter note in temperings, though it lacks nigella's oniony sharpness.

Use equal weight. Gives a similar speckled appearance and light crunch on breads, but provides a nutty rather than herbaceous, onion-like flavour.

Use 75% of the weight. Fry in hot oil or ghee; has a sharper, more pronounced liquorice flavour, so use a lighter hand.

Use 60% of the weight. Stir into the sauce with ground masalas; provides identical sweet aniseed flavour without whole seed crunch.

Use one point (single carpel) per 1 g of fennel seeds. Simmer in gravies and remove before serving; gives a deeper, woodier liquorice aroma.

Use 75% of the weight; stir in along with wet masala or tomato purée rather than frying in hot oil, as the fine powder burns instantly.

Use 50% of the weight in tempering; provides pleasant aromatic sweetness, though noticeably aniseedy rather than citrusy.

Use 15 g (1 tbsp) for every 5 g of amchoor. Stir in at the very end off the heat; adds liquid and fresh citrus aroma rather than dry fruity tang.

Use 75% of the weight, dissolved in a splash of warm water. Simmer briefly; darkens the gravy and provides a deeper, caramelised sourness.

Use 150% to 200% of the weight if matching colour, but add a pinch of black pepper or hot chilli if you need equivalent fiery heat.

Use 75% to 100% of the weight. Offers a sharp, clean heat with slightly less earthy depth and less crimson colour.

Use 50% of the weight. Mimics turmeric's warm, earthy, rhizome background, but provides none of the golden-yellow colour.

Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.
