Muthapappu

Use equal weight. It cooks in about the same time and breaks down to a similar soft, creamy consistency, though the colour will be slightly pinkish-orange.

Use equal weight. Requires longer soaking and cooking time, and produces a slightly earthier, denser dal.

Use the same weight, top and tail, and cook the same way. Closest match.

Use the same weight and trim; cooking time is the same.

Use the same weight, cut into similar lengths, and cook 2 minutes longer until tender.

Use the same weight. Peel and deseed if large; cook 5 minutes longer. Similar bland, watery flesh.

Use the same weight. Peel and deseed; similar texture, slightly firmer.

Use the same weight. Peel; firmer and holds shape better in curries.

Dry-roast lightly in a pan and grind to a fine powder; use equal weight (1:1). Offers a noticeably fresher, brighter citrus note.

Use 50% to 75% of the weight. Lacks the floral, citrusy profile of coriander and turns the gravy heavier, earthier, and darker.

Use 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.

Use about 60–70% of the weight for thickening; for coatings use the same weight but the crust is denser.

Use the same weight for coatings; contains gluten, browns faster and is less crisp.

Use the same weight for crisp coatings; coarser texture and needs a short rest.

Use 100% of the weight. Provides direct, sharp heat and red colour in equal measure.

Use 150% to 200% of the weight if matching colour, but add a pinch of black pepper or hot chilli if you need equivalent fiery heat.

Use 75% to 100% of the weight. Offers a sharp, clean heat with slightly less earthy depth and less crimson colour.

Use equal weight. Finely grind whole black or yellow mustard seeds in a spice grinder; yellow gives milder heat, black gives stronger pungency.

Use equal weight, crushed to a paste with a splash of water using a pestle and mortar. Adds a similar sharp bite.

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 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 equal weight; texture is much finer, so roast very cautiously over low heat if the recipe requires browning for spice pastes.

Finely slice or grate and use 140% of the weight to offset the extra water, or dry-roast in a bare pan until moisture evaporates completely.
