Karnatakan Mussels

Use the same weight, shelled; add in the last 2-3 minutes until pink. Texture is firmer and less briny.

Use the same weight; they cook very quickly, so add at the end and do not simmer long.

Use the same weight, cut into chunks; add 3-4 minutes before serving. Less briny, so taste and add salt.

For 100 ml wine use 25 ml white wine vinegar plus 75 ml water; simmer 2 minutes to soften the sharpness.

For 100 ml wine use 1 tbsp lemon juice made up to 100 ml with water; add off the heat. Sharper and less complex.

Use the same volume; add 1 tsp vinegar or lemon juice for acidity. Lighter, without wine's fermented depth.

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 volume or weight; slightly sweeter and less pungent, but otherwise an imperceptible swap.

Use 25% of the weight; imparts dry, fruity sourness, best stirred in right at the end of cooking.

Use 50% of the weight; delivers pleasant fruity tang but turns pale sauces considerably darker.

Use the same weight; it is neutral and will not add coconut aroma.

Use the same weight; mild and good for frying, but no coconut flavour.

Use the same weight for richness; it adds a dairy aroma and is not vegan.

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 the same weight; tear and fry in oil as usual.

Use 50% of the weight, torn; citrusy but not resinous.

Use the same weight; sweet and aniseed-like, but quite different.

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 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 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 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.
