Dum Kathhal

Use the same weight, chopped. It is softer and more acidic, so add it late in cooking or use raw in desserts.

Use the same weight, drained and chopped. It is more tart and firm; simmer briefly if the recipe is cooked.

Use the same weight, sliced. It is much softer and sweeter, so fold in at the end rather than cooking long.

Use equal weight. It handles high-heat cooking well, but lacks the signature pungent, nasal heat of mustard oil.

Use equal weight. Neutral in flavour, so your curry will lack the characteristic Bengali or North Indian pungent punch.

Use equal weight. Cut into large chunks; cooks down much faster (10-12 minutes) and softens into the sauce rather than staying starchy and firm.

Use 80% of the weight. Cube and add in the last 5-10 minutes of cooking; adds rich dairy protein instead of starchy bulk.

Use 45% dry weight. Soak overnight and boil until fully soft before stirring into the sauce to simmer for 10 minutes.

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 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 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.

Use 50% of the weight, crush or grind. Sharper heat and less maple-bitter; fry briefly in oil before adding.

Use the same weight, crush lightly. Similar bitter-seed note but more aniseed; reduce other sweet spices slightly.

Use 25–30% of the weight, crush. Much stronger thyme-like flavour; do not overdo.

Use 300% to 400% of the weight (e.g. 3–4 g paste for 1 g ground). Fry in oil alongside onions; provides a juicy, pungent kick rather than a dry, baking-spice heat.

Peel and grate finely; use 300% to 400% of the weight. Add to the hot oil early; delivers bright, peppery warmth rather than the mellow, woody heat of dry ginger.

Use 50% of the weight. Imparts a warm, spicy undertone in rich gravies, but lacks ginger's fiery, sharp zest.

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

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

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

Use 50% of the weight mixed with equal parts ground coriander and a pinch of ground cinnamon, ground cloves, and ground green cardamom. Sprinkle near the end for a warming finish.

Use 75% of the weight. Simmer briefly in the gravy; imparts roasted warmth and complexity, though it adds a slight tang and earthy lentil undertone.

Use equal weight finely chopped; this is the exact same fresh herb.

Use half the weight finely chopped; provides vibrant green freshness, though the flavour profile becomes noticeably cooler and sharper.
