I just flogged my last Meyer professional aluminium alloy pan that I originally bought to make curries in. Basically i'm not taking any chances with the possible aluminium - Alzheimer's connection. I'm dopey enough without that adding to my woes.
And, no, I don't believe there is any truth in the ali-pan being most suited for BIR results myth. The technique that works and adds to the BIR result, in any pan, is to leave the curry to boil/fry away at high heat without stirring it for a good while. That's why the chefs always seem so casual when you watch them because they know that you can/must leave the curry to cook itself for a while without being disturbed.
