Ingredients

  • 1/4 cup whole raw almonds
  • 2 cups loosely packed fresh basil leaves
  • 1 cup loosely packed fresh flat-leaf parsley
  • 12 anchovy fillets, rinsed
  • 2 garlic cloves, peeled
  • 1/4 cup plus 2 tablespoons extra-virgin olive oil
  • Zest of 1 lemon, plus lemon wedges, for serving
  • Coarse salt and freshly ground pepper
  • 12 prawns, shells and heads intact

Method

  • Preheat the oven to 350F.
  • Toast the almonds on a rimmed baking sheet in oven, stirring occasionally, until fragrant and golden brown, about 10 minutes.
  • Let cool completely; coarsely chop.
  • Process the almonds, basil, parsley, anchovies, and garlic in a food processor until combined.
  • Add the oil in a slow, steady stream, and process until smooth.
  • Transfer to a large bowl.
  • Stir in the lemon zest; season with salt and pepper.
  • Reserve 1/4 cup pistou for dipping.
  • Heat a grill to medium-high (if using a charcoal grill, coals are ready when you can hold your hand 5 inches above grate for just 3 to 4 seconds).
  • Toss the prawns with the remaining pistou.
  • Grill, turning once, until cooked through, about 2 1/2 minutes per side; season with salt and pepper.
  • Serve with the lemon wedges and reserved pistou for dipping.
