Use the same weight. Gram flour is chickpea flour, so this is an exact swap with the same nutty flavour and binding.

Use about 75–80% of the weight, e.g. 80 g for 100 g gram flour, and add a pinch of turmeric for colour. Less nutty and less crisp; good only for thickening or simple batters.

Use the same weight for crispness, but it does not bind like gram flour; mix with a little plain flour if making pakora batter.

Use the same weight straight from the pot. It is thick and slightly tangier; stir well before use.

Use about 175% of the weight and strain through muslin for 3–4 hours to yield the same weight of thick yoghurt.

Use the same weight. It is essentially the same ingredient; adjust salt or sugar to taste.

Use equal weight, whisked with a small knob of unsalted butter. Simmer gently over low heat to reduce curdling; sauce will be slightly lighter.

Use 50% weight combined with 50% whole milk, whisked until smooth. Adds intense richness, so stir in at the very end off the heat.

Use 60% cashew paste mixed with 40% warm water. Creates a silky, luxurious thickening that won't split even under high heat.

Use same weight, cut into chunks and simmer gently for 5–8 minutes; firm fish holds together well.

Use same weight and cook gently for 5–8 minutes; skinless fillet gives a cleaner texture.

Use same weight but handle very gently, as some fillets break up; simmer 5 minutes only.

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 75% of the weight. Fry in hot oil or ghee; has a sharper, more pronounced liquorice flavour, so use a lighter hand.

Use 60% of the weight. Stir into the sauce with ground masalas; provides identical sweet aniseed flavour without whole seed crunch.

Use one point (single carpel) per 1 g of fennel seeds. Simmer in gravies and remove before serving; gives a deeper, woodier liquorice aroma.

Use equal weight. Imparts an earthy, slightly bitter note in temperings, though it lacks nigella's oniony sharpness.

Use equal weight. Gives a similar speckled appearance and light crunch on breads, but provides a nutty rather than herbaceous, onion-like flavour.

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 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.

Same weight, lightly crushed; sweeter and milder but the closest match for the anise note.

Use two-thirds the weight; earthier and warmer, losing most of the aniseed character — good in breads and root vegetables.

Use half the weight; much more pungent and thyme-like, so add early in hot oil to soften it.

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.

Mash or blend to a paste; use the same weight and add a little oil if it is dry. It gives the closest sour-spiced flavour.

Mash to a paste and use the same weight; it is sharper, so reduce any extra lemon or tamarind.

Use about 70% of the weight with a pinch of chilli and salt; it gives sourness but lacks the pickle spices.

Use the same weight; taste first as it can be smokier and saltier. Add lime or amchoor if the dish needs more tang.

Use about half the weight, mixed with black salt and a pinch of ground cumin. It gives tang and saltiness but lacks the minty, asafoetida notes.

Use about half the weight and add lime juice to taste. It gives the salty, sulphurous edge but not the full tangy blend.
