Warm 27 g vegetable oil in a skillet over medium heat, tip in the tempering seeds, and stir-fry for 1 to 2 minutes until they darken in colour.
Add 12 g curry leaf and fry gently for about 30 seconds, then remove the pan from the heat.
Tip the contents of the skillet into a blender or food processor along with 36 g green chilli, 150 g onion, 2.5 g ground ginger, 2 tsp ground garlic, 175 g fresh coconut, the juice of 2 limes, the roasted sesame, and salt to taste. Blend until thoroughly ground, and consume on the day it is prepared.
Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.
Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.
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 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.
Use 50% to 60% of the weight, soaked in equal parts warm water for 15 minutes before grinding. Works well for chutneys, though texture is slightly finer and sweeter.
Use 1.2 times the weight in curries. Adds creamy richness and authentic flavour, but makes gravies smoother and eliminates the grated, chewy mouthfeel.
