Squash blossoms by John Spottiswood.

These make exquisite garnishes, but they can also be stuffed with fillings and fried, or else sautéed very briefly and put into omelettes or quesadillas. The best source of the blossoms is a garden, but non-gardeners can sometimes find them in farmers' markets or specialty markets. They don't store well, so try to use the blossoms soon after you get them.
