How to make it
Place the salmon in a glass dish, pour over the light soy sauce and leave to marinate for 1 hour.
Mix all the glaze ingredients together.
To cook, light your BBQ. If you are using charcoal make sure they are fully lit and all the flames have died down. Place your fish, skin side down, on the indirect heat of the grill.
Grill for 5 to 7 minutes, until the skin is crispy and fish is almost cooked. Flip the fish over, and grill for another minute or 2 and then flip back over. Brush liberally with the glaze and close the lid of the BBQ for a minute or 2 (you will need to take care cooking the fish as every BBQ is slightly different and salmon fillets can vary in thickness).
If you prefer to cook indoors, heat your grill to a medium and repeat the process described in steps 3 and 4.
Take the salmon off the grill, brush again with the glaze if wished, and serve immediately with a selection of grilled vegetables.
