Dum Aloo

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.

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 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 35 to 40% of the total pod weight; lightly bruise the seeds before frying in oil to release their essential oils.

Use 20 to 25% of the pod weight (about 1 generous pinch per pod); stir in toward the end of cooking so the delicate floral notes do not dissipate.

Use 1:1 by pod count or weight; crack gently before using, though it is slightly less intensely floral.

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 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.

Use 0.5 g of ground seeds for each whole pod. Stir directly into the curry base; delivers identical smoky flavour without woody husks.

Use equal pod count or weight. Crack slightly and fry whole; tastes sweet, menthol-fresh, and floral rather than dark and smoky.

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 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 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.

Dry-roast lightly in a pan and grind to a fine powder; use equal weight (1:1). Offers a noticeably fresher, brighter citrus note.

Use 50% to 75% of the weight. Lacks the floral, citrusy profile of coriander and turns the gravy heavier, earthier, and darker.

Use 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.

Use equal weight, whisked thoroughly until smooth before adding to hot dishes to prevent curdling.

Use equal weight with 1 teaspoon lemon juice mixed in. Provides rich creaminess in curries, but adds a noticeable coconut flavour.

Use 80% of the weight plus a squeeze of lemon juice for acidity. Enriches sauces nicely, though it is richer and less tangy.

Soak 2 to 3 whole stemmed chillies in hot water for 15 minutes, then blend and strain to match the specified liquid volume.

Whisk 1 tsp (3 g) of powder into warm water to match the required liquid volume; imparts identical hue with minimal heat.

Dilute 1 part purée with 2 parts water to match volume; gives rich red colour but adds extra tartness to the sauce.
