What is strawberry cube?

As an AI language model, I don't have any information about a "strawberry cube" specifically as it isn't a commonly known term or product. But generally speaking, a strawberry cube could refer to a square-shaped piece of strawberry-infused jelly or fruit gummies that are made to resemble the shape of a cube. It could also refer to a recipe or product that involves compressing and shaping cubes of fresh strawberries into a dessert or snack.
