have now cooked 2 curry sauces on the stove in "frying" mode using CA's technique (link
http://www.curry-recipes.co.uk/curry/index.php?topic=1851.0). i'm finding that i prefer it for my other cooking.
i found the stove spot on (in CA's terminology the stove is a 9Mj or 2.5kw which is well below the indicative minimum of 18Mj). my steel pan handle got hot for the 1st time ever. i don't feel i need to get the bigger jet (would be needed for Chinese).
i can't say for sure i got more "smokey/toffee" taste c/w the electric hob. it certainly was not cooked as "hot" as in the CA illustrated post. however my perception was that the curry was better (but not greatly say 2%, leaving 3% togo to BIR). the 2 family testers felt it was as good as the best i've made. we've got some friends staying over this coming week who know their curries and intend to get their opinion.
key for me is that i feel it makes for 100% consistency at the cooking stage eliminating the variation i got in the past (you know the pan is going to be hot very quickly).
i felt the heat distribution was very even (actually less splashing c/w electric hob which must be very uneven) and the turn down to simmer at the end of the frying stage spot on.
i found after cooking the 1st curry that i needed to thin the base much more than in the past and added 500ml of water to the 3L base. this gave much more evaporation during the cooking (in line with SNS & Admin's water technique which is very effective at producing that moorish taste) i need to work at this as my normal rule of thumb of 300ml base to produce 200ml finished has changed (probably more like 400ml due to the extra evaporation compared with previously).
in summary i want to be able to cook in the kitchen and electric hobs are useless for BIR cooking. a stove or burner ring is an essential (unless you have a gas hob) for getting that bit closer to BIR.
