Hi Jb, your food looks great. I'll be making some tandoori chicken tonight using your excellent recipe.
I totally agree about the oil taste. It was the big difference between my cooking and my fave local TA/Restaurant (The Saffron, Waterloo, Liverpool). If you dip your finger into the left over oil from this TA there is a wonderful moorish sweet spicy flavour.
I also agree with Russell that most BIRs probably don't prepare spiced oil specifically but it is a by product of cooking either large pots of base sauce or even the onion bhaji oil theory or both.
The spiced oil recipe we have discussed in another thread has taken my curries to a new level although there is still some fine tuning to do. I intend to buy a thermometer for oil and a spice ball to progress this further.
Cheers,
Paul
