1. Preparation
Cut 500g of beef into thin strips, about 1 inch wide.
In a bowl, mix together 3 tablespoons soy sauce, 2 tablespoons brown sugar, 1 tablespoon vegetable oil, 1 tablespoon lime juice, and 1 teaspoon ground coriander to create the marinade.
Add the beef strips to the marinade, ensuring they are well-coated. Cover and let marinate in the refrigerator for at least 20 minutes.
Soak 8 bamboo skewers in water for at least 15 minutes to prevent them from burning during cooking.
Prepare the peanut sauce by mixing together 1/2 cup creamy peanut butter, 1/4 cup coconut milk, 2 tablespoons soy sauce, 1 tablespoon lime juice, and 1 teaspoon chili paste in a small saucepan.
2. Cooking
Heat a grill or grill pan over medium-high heat.
Thread the marinated beef strips onto the soaked skewers.
Place the skewers on the hot grill and cook for about 3-4 minutes on each side, or until the beef is well-browned and cooked to your desired doneness.
While the beef is grilling, heat the peanut sauce over low heat for about 2-3 minutes, stirring until smooth.
Once cooked, remove the beef skewers from the grill and let them rest for a minute.
Serve the beef satay immediately with the warm peanut sauce on the side for dipping.
