There's not many ingredients that I've binned. Panch puran is one of them.
That's not to say I'm right.
There's something in it that has a really intense dryness taste. could never work out which of the 5 it is. Although I know it's not cumin so technically 4.
I also like onion seed (h4ppy-chris naan) which cuts it down to 3.
I think from memory fennel is an ingredient so that would get it down to mustard seed (small yellow not black) or fenugreek.
The only place I felt it might fit BIR was chef garam. Using in pre fry onion sounds decent. I guess it would be ground before using. This might also help to hide the perception of dryness in the after taste.
Must admit can't think of any more uses other than adding individually as a better strategy.
Axe once said to think to add each spice once. This was aimed at clarity and maximising flavour ie less can be more. it sits well with what I've experienced.
