Squash blossoms (the flowering part of a zucchini or squash vine) are a treat generally unavailable to all but home gardeners and habitués of farmers markets. They’re so extraordinarily perishable that few supermarkets bother trying to keep them in stock.
Here's what I did with them, along with the acorn squash they were growing with.
Washed and dried the blossoms. Sliced the squash into thick fries......made a batter of 1 cup flour, 1/2 cup cornstarch, and 1/2 cup beer. ...then fried everything in a half an inch of very hot vegetable oil. Get the full recipe here.
*UPDATE: Reader "Gay Andy" used this batter to fry tilapia in peanut oil. He said it turned out amazingly.
