Thank you Phil I will have a read, it makes me smile sometimes when you see people in third world cooking and they cook by handed down methods from their elders and somehow without the application of science they got it right.
Well, science started out as an attempt to formalise and codify the rules that govern the things that we and our ancestors have experienced in real life. After all, we wouldn't expect science to find that the best way to cook steak is to put it in a frying pan at -273C !
