Panch Phoron is a traditional spice blend originating from the Indian subcontinent, consisting of five equal parts of whole spices: fenugreek seeds (methi), nigella seeds (kalonji), cumin seeds (jeera), black mustard seeds (rai), and fennel seeds (saunf). This spice mix is commonly used in Bengali and northeastern Indian cuisine to enhance the flavour of various dishes when added to hot oil at the beginning of cooking.
