Good timing. I'm in the middle of reading The Classic Cuisine of the Italian Jews: Traditional Recipes and Menus and a Memoir of a Vanished Way of Life, by Edda Servi Machlin, who passed away just last month. Absurd prices on Amazon, but as luck would have it, Eastern Michigan University had one copy that I borrowed via our statewide interlibrary loan system. It's already inspired me to take advantage of our local in-season vegetables and make caponata tonight.
I had no idea The Key to Chinese Cooking was out of print. I'm glad I bought a copy when it wasn't. It's been a major go-to reference for me.
