This dark green soup may be served hot or cold, but served cold is perfect for summer dinner parties or that extra special picnic. Both borage flowers and leaves are edible.

From Mary Lawrence & Jane Newdick, The Miniature Book of Flowers as Food, Crescent Books, 1991. Cooking time is chilling time.
