Sabut Achari Baigan

Use the same weight; halve or quarter and cook 2–3 minutes longer. They hold their shape better in the sauce.

Use the same weight; slice or cube to the recipe's size. Similar flesh, slightly firmer.

Use the same weight; cube and salt for 10 minutes if the recipe does. It absorbs oil a little more.

Use equal weight. It handles high-heat cooking well, but lacks the signature pungent, nasal heat of mustard oil.

Use equal weight. Neutral in flavour, so your curry will lack the characteristic Bengali or North Indian pungent punch.

Use 50% of the weight, crush or grind. Sharper heat and less maple-bitter; fry briefly in oil before adding.

Use the same weight, crush lightly. Similar bitter-seed note but more aniseed; reduce other sweet spices slightly.

Use 25–30% of the weight, crush. Much stronger thyme-like flavour; do not overdo.

Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.

Use the same weight. They are milder and larger; fry a few seconds longer until they pop. The finished dish will have less pungency.

Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.

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 the same weight; fennel is the closest everyday match, slightly sweeter and milder.

Grind the same weight freshly; the aroma is stronger, so add it near the end.

Use about 50% of the weight; it is much more powerful and slightly liquorice-heavy.

Dry-roast lightly in a pan and grind to a fine powder; use equal weight (1:1). Offers a noticeably fresher, brighter citrus note.

Use 50% to 75% of the weight. Lacks the floral, citrusy profile of coriander and turns the gravy heavier, earthier, and darker.

Use 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.

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 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.
