subject: Cooking Fish on the Barbeque to Perfection! [print this page] You can wrap whole fish in foil when cooking on the BBQ as it makes for much easier handling and stops the fish sticking to the grill or plate but keep in mind we do lose the BBQ penetrating taste and the crispy film without the direct contact. Add a bit of lemon juice or a marinade mix for flavour and make a handful of slits that are about 1/8" deep on both sides of the fish as this helps to get the heat throughout your whole fish cooking it more evenly.
