I’m hoping that the “practically” in this food encyclopedia’s title refers to the encyclopedia itself and not to the food, but
in any case, it’s a potentially useful resource.
Honestly, where else can you find out about the Nottingham Goose Fair, lingonberries, and spiny lobster–all in one place?
Nowhere, that’s where! (And Wikipedia, perhaps, but then you have all that non-food information to wade through as well. Who wants to do that?)
