The late, great American cookbook author Marion Cunningham famously carried with her a photograph of a table loaded with cakes angel food cakes, all slightly different: some tall, some short, some white and fluffy, some in a Bundt shape. The photo was taken at a meeting of the Baker’s Dozen, a group of pro bakers including Alice Medrick and Carol Field who met regularly to exchange problems and solutions. Each of the cakes was baked by the members from the same recipe. “If all our results were this different,” Cunningham sympathized, “think of the plight of the poor home cook.” This recipe in question is this one, from “cookie baker for the stars,” Tom Roach, adapted with a bit of Cunningham’s gentle advice.
