i want to make homemade filled wontons. should i freeze after putting in the filling and shaping or after cooking?
Line a pan with parchment paper, lay out your filled wontons making sure they don't touch, and freeze them on the pan. Once they're frozen, transfer the wontons to a heavy-duty ziploc bag and squeeze out as much air from the bag as you can. Otherwise, your wontons will stick together in a big blob in your freezer and you won't be able to separate them without tearing your wontons. BTW, I've successfully frozen cooked wontons as well, but they don't taste nearly as good. Hope that helps!
Freeze them raw.
But freeze them in a single layer, not touching, on a tray, and put them in bags only once they are completely frozen. That way they won't stick together.
