Pumpkin Pickle

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 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 the same weight; peel and cube. Firmer and less sweet, so cook 5–10 minutes longer and taste for sugar.

Use the same weight; peel and cube. Sweeter and starchier; reduce added sugar and cook until just tender.

Use the same weight; cut larger chunks. Watery and soft, so cook 5 minutes less and reduce liquid.

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 100% of the weight. Imparts a very similar clean acidity with a faintly softer, grain-based finish.

Use 100% of the weight as a direct 1:1 replacement.

Use 100% of the weight. Stir into the sauce at the end of cooking; adds vibrant fruity acidity rather than acetic punch.

Use the same weight. It has mild molasses and is close to caster sugar with a little colour; taste and adjust.

Use 90% of the weight. It has stronger molasses, which suits dishes where jaggery was intended; dissolve fully.

Use 75% of the weight. Reduce other liquid by about 20% and add off the heat; it brings its own floral flavour.
