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 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 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, 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 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.

Use 60% of the weight, whisked smooth and added on low heat. Provides rich body and sourness, though the gravy becomes paler and creamier.

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.

Use 3 to 4 times the weight, finely chopped. Stir in towards the very end of cooking; provides a fresher, brighter herbal lift rather than deep, concentrated menthol.

Use equal weight, crushed between your palms. Offers savoury, earthy bitterness rather than cooling mint, but works nicely in marinades and rich gravies.

Use equal weight. Sauté in hot fat until the raw allium smell disappears; slightly wetter, but provides identical warmth and pungency.

Use 20% to 25% of the weight (1 g for every 4 to 5 g fresh). Stir into the gravy; adds peppery heat and warmth, though it misses the crisp, zesty kick of raw root.
