There are two ways you can make your wonton shells. One is by folding the wrappers over the oven rack and baking until stiff.  The other way allows for a crispier, more airy shell but takes time. I placed the wonton wrapper in hot vegetable oil flat...then as soon as it starts to fry and get the air bubbles, I folded it over with a fork, holding it up slightly so that it would have the opening for the stuffing.
