An American cook -- of all things -- at Chateau de Fey in Burgundy, the author records her recipes and growing fondness for Monsieur Milbert, the very French gardener, in this narrative cookbook. It includes 250 month-by-month recipes, which draw heavily on M. Milbert's garden, and some fine observations on local people and places. The chateau is owned by teacher and author Anne Willan.  (FRN85, $32.50)
