I will be going to a color-themed dinner party next month and have been assigned the color blue. Does anyone have suggestions for recipes that are blue? Blueberries are an obvious choice, and I'd love to hear people's favorite blueberry-centered dishes, but would also be curious to hear other non-blueberry ideas as well. The dish could just contain some blue elements, but something that is actually a solid blue color would be a plus. It can be a dessert or any other meal component.
