Navratan Korma

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.

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 equal weight. Fry gently in oil or ghee with the ginger; incorporates smoothly into curries without visible minced bits.

Use 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.

Use 1.5 times the weight, very finely minced. Sauté until golden; provides savoury allium sweetness, though it lacks garlic's pungent sulphur bite.

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 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 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 the same weight; cut into similar florets and cook 2–3 minutes less. It is greener and slightly stronger in flavour.

Use the same weight and break into even florets. This is essentially the same vegetable, so cooking and flavour change little.

Use the same weight; cut into wedges and cook 3–5 minutes less. It becomes much softer and sweeter, so the dish loses cauliflower's bite.

Use the same weight; peel and cut as for carrot. It is less sweet and slightly peppery, so add a pinch of sugar and expect a softer, more earthy result.

Use the same weight; cut into similar pieces and add 5–10 minutes' extra cooking. It gives bulk but no carrot sweetness or colour.

Use the same weight; cut a little larger and add near the end. It releases water, so reduce other liquid slightly and expect a softer texture.

Use equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.

Use 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.

Use 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

Use the same weight in savoury dishes; it adds body, so adjust salt.

Use the same weight only in doughs or creamy dishes; it makes the result richer.

Use the same weight in curries or rice; it adds sweetness and a faint coconut taste.

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

Same weight, peeled, cored and chopped; fresher and more acidic, so add 10 g sugar if the dish is sweet.

Same weight, chopped; identical in taste, only the cut differs.

Use 1:1 by weight; cook straight from fresh or frozen with identical timing and sweetness.

Use 60% of the weight in dry dal; boil until tender yet firm before stirring in, lending a nuttier texture rather than sweet pop.

Use the same weight, top and tail; same result.

Use the same weight; same result.

Use the same weight, cut into lengths; firmer and earthier, cook slightly longer.

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.

Grind the same weight; remove the pods first for a cleaner, stronger powder.

Grind the same weight of the seeds from green pods; discard the husks for the best flavour.

Use the same weight; it is the same spice and works directly.

Use equal weight, whisked with a small knob of unsalted butter. Simmer gently over low heat to reduce curdling; sauce will be slightly lighter.

Use 50% weight combined with 50% whole milk, whisked until smooth. Adds intense richness, so stir in at the very end off the heat.

Use 60% cashew paste mixed with 40% warm water. Creates a silky, luxurious thickening that won't split even under high heat.

Use 100% of the weight. Soak in boiling water and slip off skins before frying or grinding; gives a lighter, slightly less sweet richness to curries.

Use 60% of the weight for gravies. Soak in warm water and grind into a fine paste to thicken royal kormas without adding heavy oiliness.

Use 100% of the weight. Roast, skin, and grind; creates a thicker, earthier texture typical of Maharashtrian and western Indian curries.
