What it is
Panch phoron means "five spices", and unlike almost every other Indian blend it is used whole, never ground. Five seeds are mixed in roughly equal parts and tempered in hot oil at the start of cooking, where each releases its aroma.
The five are cumin, fennel, fenugreek, nigella (kalonji) and radhuni (or mustard as the common substitute). Together they balance earthy, sweet, bitter and pungent in a single spoon.
The blend
Simply mix equal parts of the five whole seeds and store, no roasting, no grinding.
- Cumin seeds1 part
- Fennel seeds1 part
- Fenugreek seeds · the bitter one1 part
- Nigella (kalonji)1 part
- Radhuni or mustard1 part
Traditional panch phoron uses radhuni (wild celery seed), but it is hard to find outside Bengal, so mustard seed is the usual and perfectly good substitute.
How to make it
1 · Mix equal parts
Combine the five whole seeds in equal measure. That is the whole blend, no cooking needed to make it.
2 · Store as whole seeds
Keep in an airtight jar. Whole seeds hold their aroma far longer than ground powder, easily six months or more.
3 · Temper in hot oil to use
Add a teaspoon to hot oil (mustard oil is traditional) at the start of cooking and let the seeds splutter and release their aroma.
4 · Mind the fenugreek
Keep the heat moderate, fenugreek scorches fast and turns bitter, so add your onions or vegetables as soon as the seeds pop.
A teaspoon spluttered in hot oil to start dals, vegetable dishes and pickles, especially Bengali and Odia ones. It is a tempering blend, added at the beginning, not the end.
Why these spices
Keeping the seeds whole is deliberate: bloomed in hot oil, each seed releases its fat-soluble aromas slowly and cleanly, and stays whole to give little bursts of flavour in the dish. The one to watch is fenugreek, its aroma turns from warm to harshly bitter if it browns too far, which is why panch phoron goes into moderately hot, not smoking, oil. Whole storage also means it keeps far longer than any ground blend.
The honest note
Nothing to caveat, it is just five whole seeds, and several of them (fennel, fenugreek, cumin) carry gentle digestive reputations. The only practical tips are to keep it whole until you use it, and not to burn the fenugreek. One of the easiest blends to keep on hand.
