The sausage fan--specifically of Cervelas (made of beef, bacon and pork rind) and Landjager/gendarme (a dry salami sausage)--says his all-time favourite tuck-in consists of thick slabs of veal Lyoner or saucisse de Lyon on slices of the braided bread called Zupfe/tresse.
Invite some friends over for a weekend lunch and replicate Hemingway's lunch at the Brasserie Lipp from A Moveable Feast, with pommes l'huile (potatoes in oil), cervelas (sausages) with mustard sauce, and beer.
