Use the same weight; peel and cut into chunks. It cooks much faster than cassava, so reduce simmering by 10–15 minutes and check often.

Use the same weight; peel and cut into chunks. It is sweeter and softer, so reduce cooking by about 10 minutes and adjust sugar or tamarind.

Use the same weight; peel and cut into similar pieces. It is closer in starchiness but can be firmer, so simmer until fully tender.

Use equal weight freshly grated or diced. Delivers the identical sweet, milky taste and juicy texture.

Use 60% of the weight and soak in hot water or milk for 15 minutes before using. The finished dish will be slightly sweeter and less fibrous.

Finely grate and use 50% of the weight, soaked in hot water for 20 minutes. Yields a firmer chew and a denser, oilier coconut aroma.

Use equal weight, finely chopped. Red onion matches the pungency best, though it takes slightly longer to brown and lacks shallots' subtle sweetness.

Use 20% garlic combined with 80% onion by weight; finely slice to replicate the sharp, sweet aromatic profile.

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 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 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 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.

Fry 1 bay leaf for every 5 curry leaves in hot oil; imparts a warm, woodsy background note, but misses the citrus-sulphury punch entirely.

Add a small squeeze (about 5 ml per sprig of curry leaves) right before serving; provides sharp citrus top notes without the toasty, herbal aroma.
