A thick, tangy onion and tomato chutney ground smooth and finished with a mustard-and-chilli tempering. It tastes sweet-sour from tomato and tamarind, with warm cumin and a sharp mustard kick.
Tomato-base masala
4.1 gStirred into the onion and tomato mixture (step 3)
Heat 13.5 g vegetable oil in a large heavy pan over medium heat.
Add 1500 g onion, chopped, and fry for about 10 minutes, stirring, until soft.
Add 480 g tomato, chopped, 6 g garlic, minced, 0.3 g sea salt and the tomato-base masala (2.1 g cumin seed and 2 g kashmiri chilli powder). Cook for 10–15 minutes, until the tomato collapses.
Take the pan off the heat and let the mixture cool.
Grind the cooled mixture with 4 tbsp water to a smooth paste.
For the tempering, heat 13.5 g vegetable oil in a clean pan.
Add the mustard tempering masala (3.5 g black mustard seed) and fry for about 30 seconds, until the seeds pop.
Add the dried chilli tempering masala (4 g dried Kashmiri red chilli) and 0.5–0.8 g curry leaf; fry for a few minutes until the oil smells aromatic.
Stir the ground paste and 12 g tamarind paste into the tempering. Add 2 tbsp water and mix well.
Heat until it just boils, then taste and add a little more salt if needed. Cool slightly.
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 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 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 1 g powder for every 1.5 g whole dried chilli; whisk with a spoonful of warm water and stir into the masala to provide identical ruby colour and mild heat.
