Soak 10 wooden skewers in warm water for at least 20 minutes to help prevent them from burning.
Cut the salmon into 5cm x 2.5cm/2in x 1in pieces and place onto the skewers. Arrange the salmon skewers in a single layer in a dish.
Place the honey, soy sauce and sherry or mirin into a pan and gently warm until thoroughly mixed. Remove from the heat and leave to cool then pour the marinade over the skewers and refrigerate for 1-2 hours to allow the flavours to develop.
Place on a heated barbecue for 1-2 minutes, turning frequently, until cooked. Alternatively, cook on a hot griddle for the same amount of time, also turning often. Serve drizzled with griddled lemon, if liked
