Use the same weight; peel if eating raw and salt-drain briefly. Softer and less watery.

Use 70% of the weight, grate, salt and squeeze out water. Sharper and peppery.

Use the same weight, peeled and diced; crisp but bland, so adjust salt and lemon.

Use 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.

Use 60% of the weight, whisked smooth and added on low heat. Provides rich body and sourness, though the gravy becomes paler and creamier.

Use the same weight; cook a little longer. Milder and less sweet when raw.

Use the same weight; sweeter and softer, so reduce cooking time slightly.

Use only the white parts, weight for weight, for raw or quick-cooked dishes; green parts are too grassy for long cooking.

Use the same weight; peel and cut as for carrot. It is less sweet and slightly peppery, so add a pinch of sugar and expect a softer, more earthy result.

Use the same weight; cut into similar pieces and add 5–10 minutes' extra cooking. It gives bulk but no carrot sweetness or colour.

Use the same weight; cut a little larger and add near the end. It releases water, so reduce other liquid slightly and expect a softer texture.

Use the same weight, choosing the coriander element if available. If only basil is available, expect a sweeter, more aniseed flavour.

Use the same weight. Basil is sweeter and more aromatic in a different way; add near the end so it keeps its perfume.

Use 1.5 times the weight and reduce other liquid slightly; it is less fresh and more concentrated, so taste before adding more.

Use the same weight or juice amount; sharper, so taste before adding all the juice.

Use about 45–50 ml for 1 lemon; add off the heat to keep the freshness.

Use 1 tsp for the juice of 1 lemon; add early. Sourness is flatter and less fresh.

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.

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 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.
