The bun, like a sesame freckled breast of an angel, resting gently on the ketchup and mustard below, flavors mingling in a seductive pas de deux. And then: a pickle! The most playful little pickle! Then a slice of tomato, a leaf of lettuce and a patty of ground beef so exquisite, swirling in your mouth, breaking apart, and combining again in a fugue of sweets and savor so delightful. This is no mere sandwich of grilled meat and toasted bread. This is God, speaking to us in food.
