Chef John'S Teriyaki Burgers

• 1 pound ground beef (85% lean)
• 2 tablespoons soy sauce
• 1 tablespoon sake
• 1 tablespoon mirin
• 1 teaspoon Worcestershire sauce
• 1 teaspoon sriracha hot pepper sauce
• 1 teaspoon brown sugar
• 4 slider-size burger buns
• 4 leaves lettuce
• 4 slices tomato

1. Preheat grill to medium-high heat and lightly oil the grate.
2. Break up ground beef with the tip of a fork in a bowl. Drizzle in the soy sauce, sake, mirin, Worcestershire sauce, and sriracha sauce; crumble in brown sugar. Use tines of a fork to evenly distribute ingredients. Finish mixing with your hands (ideally your hands should be very cold for this). Shape into 4 equal-sized patties.
3. Grill until browned and cooked through turning once, 3 or 4 minutes per side. When burgers develop a slight dome shape and juices begin to come through the top surface, they are done. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
4. Serve burgers on slider buns with lettuce and tomato slices.
