Cut the meat into strips about 10 cm long and 3 cm wide. Soak the wooden skewers in water so that they don`t burn so easily later on the grill.
Wash the lemongrass and cut into thin slices. Crush both with coriander seeds and cumin seeds in a mortar. Mix in the salt, pepper, 2 tablespoons of sugar, curry powder and 3 tablespoons of the thick layer on top of the coconut milk. Then season the meat with this mixture.
Cover and marinate the meat for at least 1 hour. Then stick the length of the accordion on 12 soaked wooden skewers.
Cook the skewers on the charcoal grill for about 3 minutes on each side or in the top oven at 200 ° C for about 15 minutes until they are browned, turning them frequently.
