Bring a large saucepan of water to a boil and season with salt to taste. Add 500 g pumpkin and the turmeric for boiling, simmering and stirring occasionally for 10–15 minutes until the pieces soften without turning mushy. Drain and set aside.
Heat 18 g vegetable oil in a large skillet over medium heat. Add the tempering spices and 4.3 g urad dal, stirring for about 1 minute until the mustard seeds begin popping.
Tumble in the cooked pumpkin along with 100 g jaggery. Once the jaggery starts to melt into the vegetables, scatter over 24 g fresh coconut and 4 tablespoon rice flour.
Gently turn the mixture over medium heat for another 5 minutes so the squash turns tender and evenly coated, then take the pan off the heat to serve.
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 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 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.
