They may be round or square shaped.
If you are using square, you place the filling diagonally in one corner of the wrapper.
If you are using round, just place the filling in the centre.
You buy the wrappers already to go, frozen. Thaw before use. Ideally, look for the individually separated ones.
Keep moist while working with them. A damp paper towel will do the trick.
Wonton or egg roll wrappers (won’t cook up as crisply.)
