A BK Whopper isn’t just about the burger—it’s about getting all the layers just right!The real secret is cooking the beef over an open flame. That’s what gives it that deep, grilled taste that a pan just can’t match.For the copycat I'll use iceberg lettuce for the crunch. Other types wilt too fast and don’t give the same texture when stacked under the tomato.I always toast the sesame seed bun first. It keeps the bottom from getting soggy once the mayo and tomatoes go on.Spread the mayo on both sides of the bun so every bite has that creamy contrast to the smoky beef and crisp veggies.
