Hi Onions,
I used just the right amount of liquid smoke, but the taste was all wrong. My experiment with charcoal ended up with something that tasted of paraffin - guess I didn't manage to burn off all the accelerant, but even so, I believe you when you say they don't do that in most restaurants.
I have tried every variation of frying onions, garlic, mustard seeds and dried curry leaves, both individually and together. I use butter ghee for frying. I have tried every degree of cooking, from golden brown to quite burnt. Not one experiment has produced anything remotely like the tarka dal that 90% of BIR's serve.
Onions, if you know the answer, PLEASE can you tell us?
It would be like Xmas arriving early.
Cheers
Linda
