I read an interview at The Splendid Table of Luisa Weiss, the author of Classic German Baking. Yes, it is written in English. I'm sorely tempted to buy it, but I suspect that a lot of butter is involved....
With family heritage that includes German and English, I came by my desire for multiple kinds of cookies, cakes, and breads at Christmas genetically. At least this year I have that lovely molded gingerbread and the nutcracker eggnog cakes.
