Ingredients:

1/4 cup Japanese or Korean dark soy sauce,
3 tablespoons granulated sugar,
1 tablespoon vegetable oil, plus more for grilling.
1 teaspoon sesame oil,
1 teaspoon toasted sesame seeds,
3 medium garlic cloves, crushed, peeled, and grated.
3 scallions, root and dark green ends trimmed, and 6-inch stalks minced.
2 pounds ground sirloin or ribeye steak.

Directions:

Whisk together the soy sauce and sugar in a bowl until the sugar is completely dissolved. Stir in the vegetable and sesame oils, sesame seeds, garlic, and scallions until well combined. Form patties using BurgerMate and place patties in sauce making sure it is evenly coated on both sides. Remove the beef patty after several minutes, shaking off the excess liquid and scraping off the scallion and garlic.  Grill the patties, no more than 7 minutes per side so the beef remains tender.
