This recipe is from "The Cooking of Provincial France" from the Time-Life "Foods of the World" series of books from the late 60s/ early 70s. My mother had the whole series and I remember poring over those books endlessly as she would cook from them. This particular volume was authored by M.F.K. Fisher, nonetheless! It is delicious and a bit less fuss than the scallop shell/ ramekin presentation of the cream sauce version.
