Marinate prawns with salt and turmeric powder for 5 - 10 mins. Squeeze out any remaining moisture.
In a 2 or 3 Ltr pressure cooker, layer as follows: oil, marinated prawns, kashmiri chili powder, cumin powder, coriander powder, mustard powder, fennel seed powder and garam masala. Cook on high for 3 whistles or 5 minutes (whichever comes first). Release pressure.
Mix in white vinegar and sugar and boil on medium heat for 1 min if there is excess liquid.
Cool completely and store in a clean glass jar. Instant prawn pickle is ready to enjoy as a side with rice or pulao.
Notes
This pickle can be stored in the cabinet without refrigeration for up to a month or more if refrigerated.
Transfer the cooled pickle to a ceramic or a glass jar. Metals and plastic containers tend to react to the pickle and hence using them is not recommended.
