- 1 large handful slightly stale, rustic-style bread, torn into pieces
 - large handful hazelnuts
 - 1 lemon, zest and juice
 - 125g/4oz butter, cut into small cubes
 - 2 garlic cloves, chopped
 - splash pastis
 - sea salt and freshly ground black pepper
 - large handful fresh parsley leaves, chopped
 - 30 raw signal crayfish (substitute with langoustines if unavailable)
 - lemon wedges, to serve
 
- Preheat the grill to its highest setting.
 - Place the bread into a food processor and blend into medium-sized breadcrumbs.
 - Add the remaining stuffing ingredients, except for the parsley, to the breadcrumbs and blend until thoroughly combined. (If it becomes a lump, remove the lid and break it up a little with a spoon.) Stir in the chopped parsely.
 - For the crayfish, using a sharp knife, cut all of the crayfish lengthways from tip to tail. Remove any waste sacs from the crayfish.
 - Arrange the crayfish, side-by-side, on a roasting tray. Smear up a generous amount of the stuffing onto the flesh side of each crayfish half.
 - Sprinkle the crayfish with salt and place under the grill. Grill for 4-5 minutes, or until completely cooked through. The shells will turn completely red when cooked. If there are any remaining signs of dark brown or blue colouring, they are not ready and require a few minutes more.
 - To serve, transfer the cooked crayfish to a plate, and arrange in rows. Serve with lemon wedges.
