Ingredients: 1/3 cup mayonnaise | 1 tablespoon toasted sesame seeds | 4 tablespoons unsalted butter, at room temperature | 4 brioche hamburger buns, split 2 pounds ground chuck, shaped into eight 1/4-inch-thick patties | Kosher salt | Freshly ground pepper | 2 tablespoons olive oil | 8 slices of cheddar cheese | 4 butter sticks | lettuce leaves | 4 shiso or sesame (perilla) leaves | 4 thin slices of tomato | 4 thin slices of red onion.

How to make:
Step 1
In a small bowl, mix the mayonnaise with the sesame seeds.

Step 2
Heat a large nonstick griddle or 2 nonstick skillets over moderate heat. Butter the cut sides of the hamburger buns and toast them on the griddle until golden, 4 to 5 minutes. Transfer to a platter.

Step 3
Season the patties with salt and pepper. Brush the griddle with the olive oil, add the patties and cook over high heat for 2 minutes. Flip the patties and cook for 2 minutes longer, then top each one with a slice of cheddar cheese. Cook just until the cheese is melted, about 1 minute.

Step 4
Stack 2 burgers on each bun. Top with the lettuce, shiso leaves, tomato and onion. Spread the top halves of the buns with the sesame mayo, close the burgers and serve.
