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 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; 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 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.

Use 85% of the weight; holds high cooking temperatures without smoking, but the final dish will lack traditional dairy depth.

Use equal weight; heat to smoking point and cool slightly before cooking, bearing in mind it introduces an assertive, pungent edge.

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. 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.

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 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.

Grind deseeded dried pods to an equal weight of powder; gives identical vivid red colour and gentle warmth.

Use 25% of the weight mixed with sweet paprika for colour; straight red chilli powder is substantially hotter and will make the dish fiery.

Use one-third of the weight; the sauce will be less intensely red and notably sharper in heat.

Grind the same weight; remove the pods first for a cleaner, stronger powder.

Grind the same weight of the seeds from green pods; discard the husks for the best flavour.

Use the same weight; it is the same spice and works directly.

Grate whole nutmeg finely on a microplane; use 80% to 100% of the weight. Freshly grated nutmeg has significantly more aromatic oils and a more vibrant aroma.

Use 100% to 120% of the weight. Mace is nutmeg's outer husk, providing almost identical warmth but with a lighter, slightly more delicate, floral edge.

Use 75% of the weight. Adds comparable warmth and sweetness, though it lacks the musky, nutty undertone of nutmeg.

Use the same weight, choosing the coriander element if available. If only basil is available, expect a sweeter, more aniseed flavour.

Use the same weight. Basil is sweeter and more aromatic in a different way; add near the end so it keeps its perfume.

Use 1.5 times the weight and reduce other liquid slightly; it is less fresh and more concentrated, so taste before adding more.

Use the same weight, top and tail; same result.

Use the same weight; same result.

Use the same weight, cut into lengths; firmer and earthier, cook slightly longer.

Use 1:1 by weight; cook straight from fresh or frozen with identical timing and sweetness.

Use 60% of the weight in dry dal; boil until tender yet firm before stirring in, lending a nuttier texture rather than sweet pop.

Use equal weight, pitted and finely chopped. Lends a deeper, slightly more tart sweetness to curries and rice dishes.

Use equal weight. Fry lightly in ghee until golden; substitutes the burst of sweetness with a rich, buttery crunch.

Use 30% of the weight, finely grated. Dissolve straight into the sauce to match the intended sweetness, though without the fruity chew.

Use the same weight; sharper and clearer; reduce salt slightly.

Use 90% of the weight, diluted with 10% water; harsher, so taste.

Use the same weight; fresher sourness but no malt flavour; reduce salt.

Use the same weight; it is drier and slightly less molasses-rich, so taste and add a little more if needed.

Use the same weight; it is stronger and more mineral, so dissolve it first and reduce any other sweetener.

Use the same weight; it is less moist and less dark. Add 5 g cane molasses per 100 g if you have it.

Use the same weight in savoury dishes; it adds body, so adjust salt.

Use the same weight only in doughs or creamy dishes; it makes the result richer.

Use the same weight in curries or rice; it adds sweetness and a faint coconut taste.
