I don't want to seem like a 'party-pooper' but I feel that this thread is being hijacked somewhat! It sems to turning into a general forum about technique, as opposed to questions about Bruce's stuff. None of my business I know, I'm not a moderator!
I recall Bruce is quite specific about generating the required heat for cooking. It may well be that an electric hob is not up to the job, but I believe that practically any gas hob IS! I think that provided spices are fried 'till the "toffee" smell is produced it does not really matter how fierce your flames are!!
I have a 6 ring Smeg hob, now as it happens, I don't think it's 'much cop' for a variety of reasons ('wouldn't get another!) BUT it does have several sizes of burner, including a so-called wok burner for hight heat. This burner is no where near the output of the sort of thing used in a commercial kitchen, but never the less it does kick out some joules!
I've tried frying my spices by a variety of methods:-
- Over a moderate heat in a heavy cast frying pan on a 'normal' ring
- In a wok over the wok ring, in a light thin wok, on the wok ring
I have found that provided I stop when I get the right smell, it makes NO difference to the final taste! It is slighty eaier to ruin the spice by burning in the wok on the high heat, because it has less thermal inertia and can overheat quickly. But that's it, end of story! I made a Bhuna last night, and the kitchen still had the BIR TA smell this morning.
I DON'T believe I'm an expert, and what I have learnt has largely been due to this site, BUT I REALLY BELIEVE THIS QUESTION OVER USING HIGH OUTPUT BURNERS IS BARKING UP THE WRONG TREE!
