Use the same weight, topped, tailed and cut into similar pieces. It is firmer and less mucilaginous; cook a few minutes longer until tender.

Use the same weight, trimmed and cut into short lengths. It cooks faster and stays crisp; add towards the end and expect no okra stickiness.

Use the same weight, cut into small pieces and cook until soft. It gives a soft, seedy texture but no okra mucilage and absorbs more oil.

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 equal weight; grind freshly in a mortar or spice mill for an even more vibrant camphor-and-smoke aroma.

Use 2.5 times the weight in whole pods; crack open, extract the sticky seeds, and grind to a fine powder, discarding the husks.

Use 60% of the weight; provides some warm resinous smokiness if it contains black cardamom, though it adds cinnamon and clove notes.

Grind whole seeds finely; use equal weight (1:1). Provides a fresh, sweet, aniseed aroma that is slightly stronger than pre-ground powder.

Grind finely; use 75% to 80% of the weight. Has a sharper, sweeter liquorice taste with less of fennel's herbal earthiness.

Grind whole star anise finely; use 30% to 40% of the weight. Very potent aniseed flavour that easily overpowers a dish if not used sparingly.

Dry-roast briefly and grind finely; use equal weight (1:1). Imparts an even punchier, nuttier, toasty aroma than pre-ground cumin.

Use equal weight (1:1). Adds mild, lemony sweetness rather than cumin's smoky, earthy bite; curries will taste lighter and less savoury.

Grind finely; use 60% to 75% of the weight. Produces a darker, more complex, smoky-herbal flavour suited to rich gravies.

Use 1:1 by weight; pulverise in a spice mill or mortar to a fine powder for immediate, punchy heat.

Use equal weight; offers the same bite, though it gives a visibly speckled finish and firmer crunch.

Use equal weight; handles high tempering heat well and keeps flavours neutral.

Use equal weight; cook over gentle heat to prevent browning the milk solids too quickly.

Use 15 g (1 tbsp) for every 5 g of amchoor. Stir in at the very end off the heat; adds liquid and fresh citrus aroma rather than dry fruity tang.

Use 75% of the weight, dissolved in a splash of warm water. Simmer briefly; darkens the gravy and provides a deeper, caramelised sourness.

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 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.

Grate whole nutmeg finely on a microplane; use 80% to 100% of the weight. Freshly grated nutmeg has significantly more aromatic oils and a more vibrant aroma.

Use 100% to 120% of the weight. Mace is nutmeg's outer husk, providing almost identical warmth but with a lighter, slightly more delicate, floral edge.

Use 75% of the weight. Adds comparable warmth and sweetness, though it lacks the musky, nutty undertone of nutmeg.

Use equal weight, finely sliced. Shallots soften and brown faster, giving a slightly sweeter and more delicate base to curries.

Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.

Use equal weight, whisked thoroughly until smooth before adding to hot dishes to prevent curdling.

Use equal weight with 1 teaspoon lemon juice mixed in. Provides rich creaminess in curries, but adds a noticeable coconut flavour.

Use 80% of the weight plus a squeeze of lemon juice for acidity. Enriches sauces nicely, though it is richer and less tangy.
