This is a vegetarian burger that does not mimic the texture or look of ground meat, but it isn’t meant to. It’s more like the most excellent refried beans. Though you can serve this well-seasoned patty like a traditional burger, on a bun with the usual condiments, it is at its best topped with a fried egg. Dusted with fine cornmeal, the burgers are pan-fried as the mixture is too soft to grill. After frying, they are baked until crisp. For convenience, they may be fried in advance and reheated.
