Roast patiently. Roast the chillies, coriander, cumin, urad dal and peppercorns separately until fragrant, and the fenugreek lightly without letting it burn. Roast the curry leaves until dry and crisp.
Let everything cool. The ingredients should be completely cool before they go into the mixer.
Grind finely. Grind the roasted ingredients with the turmeric and hing into a fine powder.
Keep it ready. Transfer to a clean, dry, airtight jar. Use a dry spoon each time.
