Punjabi Haldi Adrak ka Achar

Use equal weight. Pop in hot fat until they crackle and turn greyish; yields an almost identical nutty, pungent finish.

Use equal weight. Fry over medium heat; delivers a milder, sweeter pop and turns bitter quickly if the oil is excessively hot.

Use 50% of the weight, crush or grind. Sharper heat and less maple-bitter; fry briefly in oil before adding.

Use the same weight, crush lightly. Similar bitter-seed note but more aniseed; reduce other sweet spices slightly.

Use 25–30% of the weight, crush. Much stronger thyme-like flavour; do not overdo.

Use equal weight. It handles high-heat cooking well, but lacks the signature pungent, nasal heat of mustard oil.

Use equal weight. Neutral in flavour, so your curry will lack the characteristic Bengali or North Indian pungent punch.

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.

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 30% of the weight; ground is more concentrated and earthy, so add early and adjust salt.

Use 30% of the weight; it is the same as ground turmeric.

Use the same weight; grate or pound it, as it is the same root.

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; sharper and less floral, so reduce any extra souring slightly.

Use about 30 g juice per lime (2 tbsp), strain pips; add at the end for fresh sourness.

Use 1 g amchoor for about 15 g lime juice; add early with spices; gives dry mango sourness, not citrus aroma.

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