Achras

Use equal weight; scrape off the skin and grate or finely julienne according to the recipe.

Use equal weight; stir straight into the sizzling aromatics, taking care as the extra moisture may spit.

Use 15 to 20% of the weight; add alongside ground spices, noting it imparts warm, dry heat rather than zesty freshness.

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 100% of the weight. Provides direct, sharp heat and red colour in equal measure.

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.

Use equal weight; handles high tempering heat well and keeps flavours neutral.

Use equal weight; cook over gentle heat to prevent browning the milk solids too quickly.

Use equal weight, finely sliced. Shallots soften and brown faster, giving a slightly sweeter and more delicate base to curries.

Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.

Use equal weight; crush or finely grate to a smooth pulp to replicate the same fresh, pungent moisture in your base gravy.

Use 20 to 25% of the weight; mix with a teaspoon of water before adding to oil so it does not burn, noting it lacks the fresh bite.

Use equal weight; peel and grate very finely on a microplane or pound to a fine paste in a mortar.

Use equal weight; mince finely and crush with the flat of a knife before frying.

Use 20% of the weight; add directly with the dry spice powders, though it yields an earthier, less pungent profile.

Use equal weight of pork shoulder or collar; cut into identical cubes and braise, reducing cooking time by 15-20 minutes.

Use equal weight of bone-in chicken thighs; curry simmers in roughly 25 minutes instead of over an hour, with a much lighter sauce.

Use the same weight; peel and slice. Practically interchangeable.

Use the same weight; peel and grate. Close, but may be slightly less sour.

Use the same weight; peel and deseed. More sour, so reduce lime or amchoor.

Use 10 to 15% of the weight (about 1/4 teaspoon per chilli); imparts dry pungent heat and reddens the dish without the grassy crunch.

Use 1 dried pod per fresh green chilli; snap in half and temper in hot oil for a deeper, toastier heat.

Use about 30% of the weight of fresh mint. Rub between your palms to crush before stirring in; the flavour will be more intensely herbal and less bright.

Use equal weight, finely chopped. Adds fresh citrusy green notes, but lacks the cooling menthol lift.

Use the same weight and crush or grind as the recipe needs; whole peppercorn is the same spice.

Use the same weight; add nearer the end if the recipe calls for whole pepper, as ground loses aroma faster.

Use about 75–80% of the weight; it is milder and earthier, with less bite.

Use 1.5–2 times the weight; it has a similar warm pungency but is milder and rounder, so the dish loses clove’s sharp medicinal heat.

Use the same weight; it gives warmth but is sweeter and lacks clove’s strength, so use only if the amount is small.

Use equal weight; grind freshly in a mortar or spice mill for an even more vibrant camphor-and-smoke aroma.

Use 2.5 times the weight in whole pods; crack open, extract the sticky seeds, and grind to a fine powder, discarding the husks.

Use 60% of the weight; provides some warm resinous smokiness if it contains black cardamom, though it adds cinnamon and clove notes.

Use the same weight, about 50 g per egg. Boil 9–10 minutes, cool and peel; exact substitute.

Use the same weight. Leaner and less rich; mash with a little oil or yolk if the dish needs richness.

Use the same weight; press and cube. No egg flavour, so add 5 minutes before the end and adjust salt.
