The novel The Paris Library had many food references that made my mouth water: buttery almond flavored fananciers, chocolate dipped cigarettes russes cookies, the lovely French cream puffs called profiteroles, and coffee soaked operas cakes.
In Chapter 12 of the novel, Odile serves Lily a croque monsieur, that they ate with forks and knives since there was a layer of bubbling Swiss cheese on the top. Yum, that brought back memories of eating lovely meals with my late husband at sidewalk cafes in Paris.
In simple terms a Croque Monsieur is a ham and cheese sandwich with bechamel sauce. It is oven baked until the cheese is gooey and stretchy. This is classic French comfort food. They are even better when served with a lovely French Chardonnay or Chablis. Bon Appetit!
