Soak wooden skewers in a bowl of water for 15-20 minutes. You want to ensure they are well soaked so they don’t burn on the grill.
Prepare the pesto. In a food processor, combine the basil, nuts, garlic, lemon juice and salt, and blitz until a paste forms.
Slowly add the olive oil in batches until a smooth consistency is reached.
In a bowl, season the raw shrimp with a pinch of sea salt and cover with pesto. You can allow the mixture to marinate for 1-2 hours if you like, but this can also be used immediately. Ensure the shrimp is well coated with the pesto.
Once the skewers have soaked, thread 5 shrimp onto each skewer and set aside.
Place skewers onto the BBQ or grill pan on a medium heat for 3-4 minutes per side. Cook until shrimp is not longer opaque and has a slight pink colour.
