A fiery, pungent raw mango pickle from Telangana loaded with ground mustard and dried chillies. It is intensely savoury, tart, and steeped under a preserving layer of oil.
Mustard spice
1000 gGround and mixed into the spice paste (step 2)
Place 250 g raw mangoes (stoned and cut into 2.5-cm / 1-inch pieces) into a clean ceramic or stone vessel. Spread 1000 g ground chillies and salt to taste across clean, dry kitchen towels to ensure every trace of moisture has evaporated.
Prepare the mustard spice, then combine it in a large bowl with the dried ground chillies and salt. Stir in a splash of oil to bring the mixture together into a paste.
Tip the spice paste and the whole fenugreek into the vessel with the raw mangoes. Drape a clean cloth over the top and leave undisturbed for 12 hours while the fruit draws out liquid.
Gently decant and discard the expelled liquid. Pour in oil until it sits 8–10 cm (3–4 inches) above the fruit, mix thoroughly using a completely dry wooden spoon, and ensure a 10 cm (4-inch) layer of oil remains resting over the top of the pickle.
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.
