It’s juicy and has just the right amount of zesty flavor—it’s like a flattened, elongated chicken nugget. Most importantly—the mayonnaise. Burger King is not afraid to liberally spread mayo on both sides of the long bun. I’m guessing it’s like three tablespoons worth of sweet, sweet mayo. My scientific theory: The almost excessive amount of mayonnaise not only adds an extra dose of umami, but also acts as some sort of flavor sealant. I don’t see a Chick-fil-A offering such scientific advances, that’s all I’m saying.
