Grilled Sea Bream with Coconut & Coriander Chutney

Use the same weight; score the skin and cook for a similar time, checking that the flesh at the bone is opaque.

Use the same weight; it is oilier and stronger, so reduce cooking by a few minutes and serve with lemon.

Use the same weight of any firm whole fish; adjust cooking by thickness, not just weight.

Use the same weight; sharper and less floral, so reduce any extra souring slightly.

Use about 30 g juice per lime (2 tbsp), strain pips; add at the end for fresh sourness.

Use 1 g amchoor for about 15 g lime juice; add early with spices; gives dry mango sourness, not citrus aroma.

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. Pop in hot fat until they crackle and turn greyish; yields an almost identical nutty, pungent finish.

Use equal weight. Fry over medium heat; delivers a milder, sweeter pop and turns bitter quickly if the oil is excessively hot.

Use 100% of the weight. Soak for at least 1 hour; takes about 10 minutes longer to cook through and has a marginally earthier flavour.

Use 100% of the weight. Reduces cooking time by about 10 minutes and breaks down softer, giving a smoother consistency rather than distinct grains.

For tempering or tadka only: use 70% of the weight. Browns faster in hot oil, providing a nutty, crunchy 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 g powder for every 1.5 g whole dried chilli; whisk with a spoonful of warm water and stir into the masala to provide identical ruby colour and mild heat.

Use 35% to 40% of the weight; discard seeds before tearing into oil to temper. Delivers a much fiercer heat, with significantly less red colouring.

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 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 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 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 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 the same weight. It is slightly coarser, so stir a little longer to dissolve; in baking, grind briefly if a fine texture matters.

Use the same weight, but dissolve it earlier as it is coarser. It adds a light caramel note and a little colour.

Use the same weight; crush or grate jaggery first. It darkens the dish and adds molasses flavour, so reduce other liquid slightly.

Use the same weight; the difference is only the order of the names.

Mix with an equal weight of ginger paste and use the same total weight.

For 20 g paste use about 10 g crushed garlic and 10 g grated ginger root with a splash of water. Add a little extra water if the dish looks dry.

Use equal weight. Imparts an earthy, slightly bitter note in temperings, though it lacks nigella's oniony sharpness.

Use equal weight. Gives a similar speckled appearance and light crunch on breads, but provides a nutty rather than herbaceous, onion-like flavour.

Use 75% of the weight. Fry in hot oil or ghee; has a sharper, more pronounced liquorice flavour, so use a lighter hand.

Use 60% of the weight. Stir into the sauce with ground masalas; provides identical sweet aniseed flavour without whole seed crunch.

Use one point (single carpel) per 1 g of fennel seeds. Simmer in gravies and remove before serving; gives a deeper, woodier liquorice aroma.

Same weight, lightly crushed; sweeter and milder but the closest match for the anise note.

Use two-thirds the weight; earthier and warmer, losing most of the aniseed character — good in breads and root vegetables.

Use half the weight; much more pungent and thyme-like, so add early in hot oil to soften it.

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.
