Chharra 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.

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.

Use 100% of the weight. Provides direct, sharp heat and red colour in equal measure.

Use 150% to 200% of the weight if matching colour, but add a pinch of black pepper or hot chilli if you need equivalent fiery heat.

Use 75% to 100% of the weight. Offers a sharp, clean heat with slightly less earthy depth and less crimson colour.

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 1:1 by weight; pulverise in a spice mill or mortar to a fine powder for immediate, punchy heat.

Use equal weight; offers the same bite, though it gives a visibly speckled finish and firmer crunch.

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 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.

Use the same weight; fennel is the closest everyday match, slightly sweeter and milder.

Grind the same weight freshly; the aroma is stronger, so add it near the end.

Use about 50% of the weight; it is much more powerful and slightly liquorice-heavy.

Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.

Use 85% of the weight; holds high cooking temperatures without smoking, but the final dish will lack traditional dairy depth.

Use equal weight; heat to smoking point and cool slightly before cooking, bearing in mind it introduces an assertive, pungent edge.

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 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 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.

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.
