Aloo ki Tarkari

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 20% of the weight; stir in during tempering rather than crushing over at the end, and be cautious as it turns bitter easily.

Crush lightly and fry in the initial oil tempering, using 25% of the weight; provides bitter notes but lacks leafy aroma.

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 briefly and grind finely; use equal weight (1:1). Imparts an even punchier, nuttier, toasty aroma than pre-ground cumin.

Use equal weight (1:1). Adds mild, lemony sweetness rather than cumin's smoky, earthy bite; curries will taste lighter and less savoury.

Grind finely; use 60% to 75% of the weight. Produces a darker, more complex, smoky-herbal flavour suited to rich gravies.

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 15 g (1 tbsp) for every 5 g of amchoor. Stir in at the very end off the heat; adds liquid and fresh citrus aroma rather than dry fruity tang.

Use 75% of the weight, dissolved in a splash of warm water. Simmer briefly; darkens the gravy and provides a deeper, caramelised sourness.

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 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 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 a 2 cm piece (about 1 g) for every 1 to 2 bay leaves. Fry in whole-spice temperings; provides the cassia-like warmth typical of Indian tejpatta.

Use 0.5 g per leaf. Stir into the sauce during simmering; gives the same warm woodiness but darkens the colour slightly.

Use equal weight; scrape off the skin and grate or finely julienne according to the recipe.

Use equal weight; stir straight into the sizzling aromatics, taking care as the extra moisture may spit.

Use 15 to 20% of the weight; add alongside ground spices, noting it imparts warm, dry heat rather than zesty freshness.
