Food more than anything shows up cultural and geographic differences. Why should the Joy have much to saw on the subject of cooking celeriac when it's a rare import food on that side of the ocean? Peanut butter is a staple comfort for many North Americans in a way alien to Brits. Cookbooks more than anything reflect this difference. Also, I grew up cooking with cup measures and sticks of butter, cooking by volume, not by weight. I only recently acquired a kitchen scale, for a while. Really recently - this past Christmas, six weeks or so ago.
So Brits (and anyone else who wants to answer this about their own childhood and their own country) - what are the all-purpose, exhaustive-to-whatever-degree cookbooks you turn to when you need to learn or refresh a cooking basic (how many minutes to boil broccoli, how to truss a chicken)? Did you grow up with it, or find something else, something which better suited your cooking interests, along the way?
