A fiery and intensely tangy preserve of sliced tamarind simmered with garlic, vinegar, and aromatic tempering spices. It delivers a sharp, sour punch balanced by rich garlic and warming chilli heat.
Remove the seeds from 500 g tamarind and cut the pulp into slices.
Warm 250 g oil in a large frying pan over medium heat. Add the whole chillies and stir-fry for 1 to 2 minutes, until they turn slightly darker.
Add the mustard seeds and fry for about 1 minute until they begin to pop. Stir in 6 g curry leaf and 18 g garlic, then place a lid on the pan.
Cook covered for 3 to 4 minutes until the garlic turns light brown. Remove the lid, add the garlic paste, and fry for 2 to 3 minutes.
Stir in the chilli powder and salt to taste, cooking for 1 minute. Add the prepared tamarind and cook for 2 to 3 minutes, then pour in 2 tablespoon vinegar and stir thoroughly.
Take the pan off the heat and allow the mixture to cool to room temperature. Pack into sterilised jars, pouring in extra oil if needed to ensure the surface is completely submerged, and store in the fridge for up to 3 weeks.
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 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.
