Ginger Pickle

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 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.

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.

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 120–150% of the weight and strain; pulp is less concentrated, so simmer a little longer to thicken.

Use 150–200% of the weight and reduce gently; extract is already diluted.

Use 60–70% of the weight with a pinch of jaggery; sharper, so add near the end off the heat.

Use the same weight. It has mild molasses and is close to caster sugar with a little colour; taste and adjust.

Use 90% of the weight. It has stronger molasses, which suits dishes where jaggery was intended; dissolve fully.

Use 75% of the weight. Reduce other liquid by about 20% and add off the heat; it brings its own floral flavour.
