Hi troops,
Just a quick note on the "toffee smell" that everyone seeems to be talking about. I had been reading about oil recycling on this forum so I decided to give it a try. I was using the last of annams base an adapted CTM recipe from KD CS. I used lamb as the meat ingredient. At the end of cooking I skimmed some of the oil off into an old plastic TA container. I had a sniff at the end of cooking and it smelt ok but nothing special. I also noted that during skimming some of the base sauce inevitably gets in there. I popped it in the fridge and forgot about it for a few days. I was making up new base so I decided to chuck it in for effect. When I opened the lid of the container POW! A "Toffee Spicy Like smell" that to be honest I don't know if I had smelled before in the curry. I just wonder if you were say to take 500mls of oil and heat it to high temp then add some ginger/garlic paste, a few spices such as methi, cumin, salt and a ladle of onion base. Then fry the hell out of it to caremalise the onion base. Cool it, stick it in the fridge to let it mature. Then use this to fry our curries in. Would this give the taste we seek? I shall try and report back ;D
