Acha Kozhi

Use 100% of the weight, cut into equivalent bone-in or boneless pieces. Simmer for an extra 5 to 10 minutes; flavour and texture are very similar.

Use 100% of the weight. Cut into bite-sized pieces and extend simmering time by 35 to 50 minutes, adding extra liquid to allow the meat to tenderise.

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 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 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.

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 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 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.

Use equal weight. Fry gently in oil or ghee with the ginger; incorporates smoothly into curries without visible minced bits.

Use 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.

Use 1.5 times the weight, very finely minced. Sauté until golden; provides savoury allium sweetness, though it lacks garlic's pungent sulphur bite.

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.

Use 1:1 by weight; pulverise in a spice mill or mortar to a fine powder for immediate, punchy heat.

Use equal weight; offers the same bite, though it gives a visibly speckled finish and firmer crunch.

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.
