Sticky Tamarind Sauce
Slice the bread and spread the burger buns with butter, then cook until crisp and set aside. Next, heat a pan and cook the beef patties until both sides are evenly cooked. In a small bowl, combine tamarind, orange juice, honey, and soy sauce, then stir well. Heat oil in a pan, sauté the shallots and garlic until fragrant, then add the prepared mixture along with orange peel and star anise. Stir well and cook until the sauce thickens. Once ready, spread the sticky tamarind sauce generously over the surface of the beef patties. Finally, assemble the burgers in the toasted buns with your favorite toppings such as salad, tomato, cheese, and onion, then serve.
