Mixed vegetables
  • Mixed seasonal vegetables

    Use the same weight; cut into even pieces and adjust cooking time by what is in season.

  • Cauliflower

    Use the same weight with carrot or green bean if possible; cut small and allow 5–8 minutes extra cooking.

  • Frozen peas

    Use the same weight; they cook fast, so add in the last 5 minutes and adjust salt.

Onion
  • Shallot

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

  • Cabbage

    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.

Coconut milk
  • Single cream

    Use equal weight; simmer gently over low heat to prevent curdling. Imparts a comparable rich texture, though it adds dairy richness without any coconut fragrance.

  • Cashew paste

    Whisk 1 part cashew paste with 2 parts water to match the consistency, then use equal weight. Provides a thick, velvety body without coconut flavour.

  • Whole milk

    Use equal weight, but reduce other cooking liquids by 20% to compensate for the lower viscosity. The curry will be lighter and lack sweetness.

Curry leaf
  • Bay leaf

    Fry 1 bay leaf for every 5 curry leaves in hot oil; imparts a warm, woodsy background note, but misses the citrus-sulphury punch entirely.

  • Lime juice

    Add a small squeeze (about 5 ml per sprig of curry leaves) right before serving; provides sharp citrus top notes without the toasty, herbal aroma.

Vegetable oil
  • Peanut oil

    Use 1:1 by weight. Handles high-heat frying identically and introduces a very subtle, pleasant nuttiness.

  • Ghee

    Use 1:1 by weight. Yields a much richer, authentic aroma and a glossy, heavier mouthfeel.

  • Mustard oil

    Use 1:1 by weight. Heat until smoking, then cool slightly before cooking to temper its intensely pungent, sharp mustard kick.

Ginger
  • Fresh ginger

    Use equal weight; scrape off the skin and grate or finely julienne according to the recipe.

  • Ginger paste

    Use equal weight; stir straight into the sizzling aromatics, taking care as the extra moisture may spit.

  • Ground ginger

    Use 15 to 20% of the weight; add alongside ground spices, noting it imparts warm, dry heat rather than zesty freshness.

Ground black pepper
  • Black peppercorn

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

  • Coarsely ground black pepper

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