Gooseberry Chutney

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 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 1 g powder for every 1.5 g whole dried chilli; whisk with a spoonful of warm water and stir into the masala to provide identical ruby colour and mild heat.

Use 35% to 40% of the weight; discard seeds before tearing into oil to temper. Delivers a much fiercer heat, with significantly less red colouring.

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; it is more sour and astringent, so taste and add sugar. Good for chutney or pickle.

Use the same weight, sliced; add a little lemon juice to sharpen. Softer and less astringent.

Use the same weight, grated; sharper sourness, so reduce any lemon or tamarind in the recipe.

Use the same weight. It is slightly coarser, so stir a little longer to dissolve; in baking, grind briefly if a fine texture matters.

Use the same weight, but dissolve it earlier as it is coarser. It adds a light caramel note and a little colour.

Use the same weight; crush or grate jaggery first. It darkens the dish and adds molasses flavour, so reduce other liquid slightly.
