Haldi, are you saying NOT to use oil that has been used for bhajis? Just chips and chicken?
From what I have seen, the main thing cooked in most places is chips, chips and more chips.
Bhajees & samosas and chicken too but not anything like the quantity of chips.
I think the main thing is that the oil is well used
This means after it's cooked in the curry gravy, you can cook on high without burning anything.
It's smoking point is drastically reduced.
I have watched chefs cooking curries and it's always in this unhurried fashion.
Whenever I tried to duplicate this at home, things burnt easily
Especialy garlic and tomato puree.
The only way to get a BIR result, is to follow their cooking style.
Anyone who has been in a BIR kitchen will have seen the pot of curry gravy.
The oil on top is really dark
Far darker than boiling fresh oil with onions and spices
Thanks Jerry and Gary for your comments
