Rajma

Use equal weight. Soak overnight and boil until tender; texture is firmer and nuttier, but it carries thick, spiced gravies equally well.

Use equal weight, soaked overnight and pressure-cooked. Yields a creamier, starchier gravy with an earthier taste rather than distinct, firm beans.

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 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.

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.

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 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 300% to 400% of the weight (e.g. 3–4 g paste for 1 g ground). Fry in oil alongside onions; provides a juicy, pungent kick rather than a dry, baking-spice heat.

Peel and grate finely; use 300% to 400% of the weight. Add to the hot oil early; delivers bright, peppery warmth rather than the mellow, woody heat of dry ginger.

Use 50% of the weight. Imparts a warm, spicy undertone in rich gravies, but lacks ginger's fiery, sharp zest.

Use 100% of the weight. If the original recipe relies on salted table butter, add a pinch of salt to balance.

Use 80% to 85% of the weight. Ghee is pure butterfat with moisture removed; it yields a deeper, nuttier flavour and handles high heat better.

Use 80% of the weight for frying or tempering. The dish loses sweet dairy richness but remains glossy and light.

Use 1:1 by weight. Functionally identical as an accompaniment or base.

Weigh out 40% of the required cooked weight in raw basmati rice, rinse, and boil in double its weight of water until tender.
