Here’s the recipe for the miraculous soufflé that Daisy Bonner prepared the day that her beloved president, Franklin D. Roosevelt, died. Bonner always served this dish with stuffed baked tomatoes, peas, plain lettuce salad with French dressing, Melba toast, and coffee.
Baked in butter and then crowned with more of it, this puffy golden pancake is similar to a popover in texture with a moist eggy interior and crispy outside. And good for breakfast or dessert, depending how you top it.
