Remove 4 segments from the lemongrass stick and cut each segment in the middle lengthwise 3 cm, so that the taste can transfer to the scampi.
Now skewer 5 scampi and 4 slices of garlic alternately onto a lemongrass stem.
Season the finished lemongrass skewers with Cajun spice and salt, grill on a hot charcoal grill for 1 minute on each side and sprinkle with some lemon juice before eating.
