Ginger-Marinated King Prawns with Turmeric, Mustard & Chilli

Use the same weight; split or halve if large. Same sweet shellfish flavour, similar cooking time.

Use the same weight; they may need 1 minute less cooking. Slightly less sweet.

Use the same weight, cut into chunks and add 2-3 minutes later. Flakes easily and lacks prawn juice.

Use the same weight; pure fat, so use as directed. Add a pinch of paprika for colour; no smoke.

Use the same weight; lower smoke point, so keep the heat moderate. Add salt if unsalted.

Use 90% of the weight; neutral and will not burn, but lacks butter or ghee flavour. Add paprika for colour.

Use the same weight and whisk smooth; same thick consistency.

Use 1.25 times the weight and strain through muslin for 30 minutes; looser if not strained.

Use the same weight; virtually identical.

Use 100% of the weight. Many commercial gram flours are milled from split peas; performs identically in pakora batters and kadhi.

For crisping batters or binding cutlets: use 50% to 60% of the weight. Produces a very crisp shell but lacks the earthy, roasted nutty flavour of besan.

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 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 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.

Use 300% to 400% of the weight (e.g. 3–4 g paste for 1 g ground). Fry in oil alongside onions; provides a juicy, pungent kick rather than a dry, baking-spice heat.

Peel and grate finely; use 300% to 400% of the weight. Add to the hot oil early; delivers bright, peppery warmth rather than the mellow, woody heat of dry ginger.

Use 50% of the weight. Imparts a warm, spicy undertone in rich gravies, but lacks ginger's fiery, sharp zest.
