The Truffle Cookbook starts with a quick education in truffles – what they are, how they’re grown and harvested and how to buy them. And there are dishes here that will satisfy accomplished cooks and sophisticated palates – chicken broth with marrow and truffle dumplings, for example.

In his book The Ultimate Sandwich, Jonas Cramby cites the French croque, the Swedish smørrebrød, the Chinese bao and the Vietnamese bahn mi, as well as American derivations like the hero, the po’ boy and the mufaletta.
