Dahiwali Lauki

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. 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 double the weight. Stir into hot oil just before adding wet ingredients; mimics the allium savoury background without the sulphurous edge.

Use 2 g for every 0.5 g of asafoetida. Sauté in oil until the raw smell clears; adds moisture and sweet allium depth.

Use the same weight; peel, deseed and cut to the same size. It holds shape slightly better, so give it 2–3 minutes more.

Use the same weight; peel and deseed. It is softer and waterier, so cook 3–4 minutes less and reduce added water.

Use the same weight; peel and deseed. It is sweeter and softens faster, so cook 3–5 minutes less.

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.

Use the same weight; this is only a spelling difference. Adjust salt or sugar as needed.

Use the same weight. It is a good ready-made thick yoghurt, slightly tangier.

Use about 175% of the weight and strain through muslin for 3–4 hours to yield the same weight.

Grind whole seeds finely; use equal weight (1:1). Provides a fresh, sweet, aniseed aroma that is slightly stronger than pre-ground powder.

Grind finely; use 75% to 80% of the weight. Has a sharper, sweeter liquorice taste with less of fennel's herbal earthiness.

Grind whole star anise finely; use 30% to 40% of the weight. Very potent aniseed flavour that easily overpowers a dish if not used sparingly.

Use 50% of the weight mixed with equal parts ground coriander and a pinch of ground cinnamon, ground cloves, and ground green cardamom. Sprinkle near the end for a warming finish.

Use 75% of the weight. Simmer briefly in the gravy; imparts roasted warmth and complexity, though it adds a slight tang and earthy lentil undertone.
