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 double the weight. Stir into hot oil just before adding wet ingredients; mimics the allium savoury background without the sulphurous edge.

Use 2 g for every 0.5 g of asafoetida. Sauté in oil until the raw smell clears; adds moisture and sweet allium depth.

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 70% of the weight; add with ground spices or sauce bases rather than hot oil tempering, where it scorches quickly and turns bitter.

Use equal weight for oil tempering. Delivers an earthy profile with an additional musky, smoky, and slightly bitter edge.

Use 60% of the weight for tempering; offers comparable warm aroma, but leans sweet and liquorice-like rather than savoury and earthy.

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 a 2 cm piece (about 1 g) for every 1 to 2 bay leaves. Fry in whole-spice temperings; provides the cassia-like warmth typical of Indian tejpatta.

Use 0.5 g per leaf. Stir into the sauce during simmering; gives the same warm woodiness but darkens the colour slightly.

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 0.5 g ground mace for 1 g mace blade; add towards the end of frying spices as ground powder burns much quicker than whole blades.

Grate finely, using 50% of the weight; sweeter, deeper, and slightly heavier in aroma than delicate mace.

Use 40% of the weight; stir in gently with ground spices, avoiding high direct heat to prevent bitterness.

This is the closest match; use the same weight and cook as directed until tender.

Use the same weight; it is starchier and can be slightly slimy, so peel, cube and simmer for 15–20 minutes.

Use the same weight; it is sweeter and softer, so reduce cooking time by about 5 minutes.

Use the same weight; peel and cut as for carrot. It is less sweet and slightly peppery, so add a pinch of sugar and expect a softer, more earthy result.

Use the same weight; cut into similar pieces and add 5–10 minutes' extra cooking. It gives bulk but no carrot sweetness or colour.

Use the same weight; cut a little larger and add near the end. It releases water, so reduce other liquid slightly and expect a softer texture.

Use equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.

Use 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.

Use 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

Use the same weight, top and tail, and cook the same way. Closest match.

Use the same weight and trim; cooking time is the same.

Use the same weight, cut into similar lengths, and cook 2 minutes longer until tender.

Use equal weight directly from fresh or frozen. Toss into the pan near the end of cooking to preserve sweetness and bright green colour.

Use 70% of the weight, boiled until tender but holding shape. Adds pleasant body and starch, though it lacks the juicy sweetness of fresh peas.

Use equal volume or weight; delivers almost identical sharp acidity with a faintly more aromatic, bitter-edged profile.

Use 25% of the weight (about 1 g amchoor for 4 g juice); provides clean fruity tartness without thinning the sauce.

Use 75% of the volume; gives direct sourness without any citrus floral fragrance.

Use 50% to 60% of the weight, soaked in equal parts warm water for 15 minutes before grinding. Works well for chutneys, though texture is slightly finer and sweeter.

Use 1.2 times the weight in curries. Adds creamy richness and authentic flavour, but makes gravies smoother and eliminates the grated, chewy mouthfeel.

Use equal weight whole. Fry in hot oil or ghee as tempered spice; gives a richer red colour with slightly milder heat.

Use 50% to 70% of the weight. Stir into the oil with ground spices; distributes heat evenly throughout the dish without whole chilli skins.

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 for tempering in hot oil. Lacks the floral, sweet citrus flavour of coriander, introducing warm, pungent earthiness instead.

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

Use 1 g ground for 4 g whole (or 1 small pinch per 2 to 3 whole cloves). Add with spice powders; disperses intense warmth quickly, so use with restraint.

Use 100% of the weight whole in tempering. Imparts a warm, clove-like aromatic profile combined with hints of nutmeg and cinnamon.

Use 1 pod for 3 to 4 cloves in whole tempering. Shares a camphor-like warmth and medicinal depth, though it introduces a distinct smoky undertone.

Use 75% of the weight. Add midway through simmering; spreads heat evenly through the dish instead of delivering isolated bursts.

Use 50% of the weight. Stir in near the end of cooking; significantly darkens light gravies and provides an immediate, sharp bite.

True cinnamon: thinner, papery quills, milder and sweeter. Use about 1.5 times the weight, and taste.

Use about a third of the weight (0.5 g ground for a 2.5 cm piece), stirred in with the ground spices rather than fried whole, since the powder burns quickly.

Use 60-70% of the weight; stronger and more peppery, so taste before adding more.
