Fried Squash Blossoms are a wonderful summertime Italian treat. I harvested this platterful of them last night and we fried 'em up. When served hot, and lightly browned and salted, they leave French Fries in the dust.
On summer squash like Zucchini and Yellow Squash, the blossoms on the stalks are the males, and thus expendable. However, I use both because there's always too much squash anyway.
This site explains how simple this is, using Marcella's method. We do not wash them at all, just check them for bugs inside. Photo below from that site -
