Melt the butter.

Crush the garlic cloves with salt using a mortar and pestle.

Grate the gingerroot finely.

Combine the melted butter, crushed garlic, grated ginger, red pepper flakes, soy sauce, and lemon juice in a bowl to make the marinade.

Place the shrimp in a container.

Pour the marinade over the shrimp, ensuring they are well coated.

Let the shrimp marinate for 30 minutes.

Skewer the marinated shrimp.

Cook the skewered shrimp on a barbecue or under a broiler for about 10 minutes, until pink and cooked through.

Baste the shrimp twice during cooking with the remaining marinade.

Serve the barbecued shrimp with french fries, rice, and a salad.
