You can cook frozen meat on the BBQ, but some types are better suited than others - always be sure to check the pack instructions. Thin cuts like frozen burgers fare best, while chunkier options like chicken breasts are tricky to cook evenly. Typically, frozen food will take 50 per cent longer and the best way to make sure it's cooked through is to employ the 50/50 technique, which means piling up your fuel on one side of the BBQ so you have an intense heat and an indirect one. Cook your frozen meat low and slow before searing at the end.
