Walking Margarita, If we have to eat fruit, we might as well soak it in alcohol. Slice a watermelon and lay the pieces into a baking dish. Pour a shot of Tequila over each slice, then cover the dish and refrigerate at least 3 hours, overnight is better. Check every so often, and feel free to baste with more booze. Before serving, dip edges in some coarse sea salt and maneuver the heat glass free!
