The bun has to be on point, and toasted to golden brown with the flavor of butter. The beef has to be rich and strong, yet submit to the slightest bite, the cheese deep and melted at the right time. The pickles have to bring the acid to the palate, yet be balanced with that slight sweetness. The lettuce and onions are fresh, and offer a contrast in texture. The fries have to be hot and crispy, with fresh cracked pepper and the right amount of salt. Much can go wrong, but when everything goes right, one may just achieve perfect bliss.
