Japanese-Style Beef Croquette Burger

Method

1. In a large bowl, mix ground beef, chopped onion, egg, milk, and flour until well combined.
2. Form the mixture into 4 oval-shaped croquettes.
3. In a shallow dish, mix breadcrumbs with salt and pepper.
4. Dip each croquette in the breadcrumb mixture, pressing to adhere.
5. Heat oil in a skillet over medium heat. Cook croquettes until golden brown and cooked through, about 3-4 minutes per side.
6. In a small bowl, mix mayonnaise, Dijon mustard, sugar, salt, and pepper for tartar sauce.
7. Assemble the burger by placing a croquette on the bottom bun, adding shredded cabbage, and topping with the top bun.
8. Serve with additional tartar sauce on the side.
9. Check that the ground meat reaches 71°C (160°F) throughout before serving.
