I always appreciate the out-of-print cookbooks noted in "Saveur's 100 things" list--good books with great food, readable, most likely way ahead of their time. If you like cookbooks that fit that description, Definitely seek out three by Elsie Masterton: "The Blueberry Hill Cookbook," "The Blueberry Hill Menu Cookbook," and The Blueberry Hill Kitchen Notebook. (Link to Abebooks search for her books below)
Elsie Masterton moved with her family from NYC to Vermont after WWII to start an inn and ski resort. She could not cook beforehand, but learned to cook brilliantly as an innkeeper. She was way ahead of her time--steaming vegeables, cooking pasta al dente, refusing to cook lamb beyond 140 degrees. These are great books and the writing is truly great. They read like novels. Seek out these books and enjoy!
