Lucknowi Khatte Aloo

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 70% of the weight; add with ground spices or sauce bases rather than hot oil tempering, where it scorches quickly and turns bitter.

Use equal weight for oil tempering. Delivers an earthy profile with an additional musky, smoky, and slightly bitter edge.

Use 60% of the weight for tempering; offers comparable warm aroma, but leans sweet and liquorice-like rather than savoury and earthy.

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 the same weight; heat and flavour are very close.

Use 1.5 to 2 times the weight; deseed for less heat. Larger chillies are more watery.

Use 1.5 to 2 times the weight; chop finely and adjust heat by tasting.

Use the same weight. Scrub and leave whole or halve if large; they cook in about the same time and give a similar waxy bite.

Use the same weight. Peel only if the recipe needs it; cut to the size of new potatoes so they cook evenly. The flesh is slightly more floury.

Use the same weight, cut into even walnut-sized pieces. It may break down a little more in long cooking, thickening the gravy.

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 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 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 the same weight, grind fresh. Same fruity sourness; grind finely so it disperses.

Use the same weight. Same ingredient; check for grit and add with the spices.

Use about 80% of the weight, then adjust. Sour but less fruity and less dark in colour.

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

Use equal weight finely chopped; this is the exact same fresh herb.

Use half the weight finely chopped; provides vibrant green freshness, though the flavour profile becomes noticeably cooler and sharper.
