In a blender, blend the peanut curd and water. Temper curry leaves, mustard seeds and asafoetida in a heavy bottomed pan without oil and add it to the buttermilk. Season with salt.
Variations
Buttermilk can be made with other plant-based yoghurts.
The flavourings could vary according to your preference – for example: roasted cumin powder, ginger-chilli paste, mint and coriander leaves, roasted whole cumin and asafoetida.
