Is pork butt the new pork belly? Can you freeze cheese? Whose room temperature are we talking about?

These questions are at the heart of every kitchen – and yes, you can freeze cheese, but why would you want to? Food science, etiquette, myth busting, history and common sense are all topics covered by Richard Cornish in his weekly Brain Food columns, which have been must-read for years. Brain Food is a collection of the best cooks’ conundrums and their surprising answers.

Richard Cornish is an award-winning food writer who has co-authored the bestselling MoVida cookbooks with Frank Camorra and Phillipa’s Home Baking with Phillipa Grogan.
