Panch Phoran is a five-spice mix used in India, mostly on the East coast, to flavor vegetables and legumes. This spice mix is either fried at the beginning and ingredients are added to it or fried and added as a final seasoning. The process of adding the spice at the end is called turka.
Grind all the spices to a fine powder in a spice grinder or a pestle and mortar.
Store in a small, airtight container until you need it.
