Dry roast all the dals individually. Add the peppercorns in one of the dals while roasting, and the spicy chilli in another while roasting. Roast for about 3 mins on medium heat till the colour starts to change. Once done, let it cool.
Heat some oil in a pan, add curry patta, jeera, hing and Kashmiri chilli. Roast it a bit and transfer it to a mixer with the dals and salt.
