well said einstein, delia will teach you everything you need to know, as for all the others, me and my mother have loads of their books, we use about two recipes at most from each in the end and we only follow the recipes when we cant remember them. this means alot of the recipes are subjected to a sort of chinese whispers thing where we dont cook their recipes any more, we do our own thing based on what they wrote.....oh and i dont weigh anything and i cook things til they look right rather than timing them. so to answer your question, the recipe books are more for ideas than real life, bit like nigella :-)
