I know there is a million-and-1 cookbook threads, so I apologize about starting a new one; I am hunting for a great cookbook. One more written for the techniques and 'whys' of cooking rather than just straight recipes. I want to learn more about general techniques to be applied over and over. Also more geared to a professional chef, not so much a home cook I have been eyeing titles such as; 'The cooks book' Jill Norman 'Modernist cuisine' out of my price range Please recommend!!
