Preparation:

Step1: Prepare the Beef

1. Slice the beef into thin strips, approximately 2–3 inches long and 1 inch wide.
2. In a large mixing bowl, combine lemongrass, garlic, shallots, turmeric powder, ground coriander, cumin, soy sauce, oyster sauce, sugar, and vegetable oil to create a marinade.
3. Add the beef strips to the marinade, ensuring each piece is well-coated. Cover and refrigerate for at least 2 hours, preferably overnight, for maximum flavor.

Step2: Soak the Skewers

1. While the beef marinates, soak the bamboo skewers in water for at least 30 minutes to prevent them from burning during grilling.

Step3: Make the Peanut Sauce

1. In a saucepan, combine ground peanuts, coconut milk, tamarind paste, chili paste, sugar, soy sauce, and salt.
2. Heat the mixture over medium heat, stirring continuously to prevent burning.
3. Gradually add water until the sauce reaches your desired consistency. Simmer for 5–7 minutes until the flavors meld together.
4. Remove from heat and set aside to cool slightly.

Step4: Skewer the Beef

1. Thread the marinated beef onto the soaked bamboo skewers. Do not overcrowd the skewers; leave some space between pieces for even cooking.

Step5: Grill the Satay

1. Preheat your grill or grill pan to medium-high heat. Lightly oil the grates to prevent sticking.
2. Grill the skewers for 2–3 minutes per side, turning frequently, until the beef is cooked through and has a slight char.
3. Baste the skewers with leftover marinade as they cook for added flavor.
