Borage flowers are edible and have a mild cucumber like flavor. They are frequently used as a garnish for iced teas, lemonades, and other cold summer beverages. One creative trick is to freeze the tiny flowers right inside of ice cubes which can later be added to your favorite drinks.
The flowers can also be crystallized and used to decorate cakes and other deserts. They can even be used as ingredients in tossed salads and make beautiful additions to fruit salads.
