Malabar Isthu with Pumpkin, Bitter Gourd & Cauliflower

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 1 g ground for 4 g whole (or 1 small pinch per 2 to 3 whole cloves). Add with spice powders; disperses intense warmth quickly, so use with restraint.

Use 100% of the weight whole in tempering. Imparts a warm, clove-like aromatic profile combined with hints of nutmeg and cinnamon.

Use 1 pod for 3 to 4 cloves in whole tempering. Shares a camphor-like warmth and medicinal depth, though it introduces a distinct smoky undertone.

True cinnamon: thinner, papery quills, milder and sweeter. Use about 1.5 times the weight, and taste.

Use about a third of the weight (0.5 g ground for a 2.5 cm piece), stirred in with the ground spices rather than fried whole, since the powder burns quickly.

Use 60-70% of the weight; stronger and more peppery, so taste before adding more.

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 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 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 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 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.

Use equal weight; simmer gently over low heat to prevent curdling. Imparts a comparable rich texture, though it adds dairy richness without any coconut fragrance.

Whisk 1 part cashew paste with 2 parts water to match the consistency, then use equal weight. Provides a thick, velvety body without coconut flavour.

Use equal weight, but reduce other cooking liquids by 20% to compensate for the lower viscosity. The curry will be lighter and lack sweetness.

Use the same weight; cut into similar florets and reduce cooking by 2–3 minutes. It adds a greener colour and stronger flavour.

Use the same weight; break the head into florets of the same size. Cooking time and texture are virtually unchanged.

Use the same weight; cut into chunks and cook 3–5 minutes less. It softens quickly and gives a sweeter, less nutty result.

Use the same weight; it is the same vegetable, usually a little milder. Scrape out the seeds and salt if needed.

Use the same weight; it gives no bitterness and more water, so salt and drain it briefly before cooking.

Use the same weight; it is soft and mild, so the dish loses the bitter note entirely.

Use the same weight; peel and cube. Firmer and less sweet, so cook 5–10 minutes longer and taste for sugar.

Use the same weight; peel and cube. Sweeter and starchier; reduce added sugar and cook until just tender.

Use the same weight; cut larger chunks. Watery and soft, so cook 5 minutes less and reduce liquid.

Use 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.

Use 60% of the weight, whisked smooth and added on low heat. Provides rich body and sourness, though the gravy becomes paler and creamier.

Use the same weight and crush or grind as the recipe needs; whole peppercorn is the same spice.

Use the same weight; add nearer the end if the recipe calls for whole pepper, as ground loses aroma faster.

Use about 75–80% of the weight; it is milder and earthier, with less bite.

Use equal weight; grate or shave finely so it dissolves rapidly, giving a warm, caramel-like sweetness and slightly darker sauce.

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.
