Well, I know what I did wrong.
But the family liked the filling, so I’ll try them again in the future and I’ll give you a recipe.They look good and they even didn’t taste to bad, but they are not what they are supposed to be. But this is what happens when you buy a package of loempia-leaves and it doesn’t have any instructions on it. I trew them all in a pot and poured some boiling water over them. Guess what happened: they all sticked together. I managed to save some and put a filling in them but then I shouldn’t have baked them in the oven, I guess I should have steamed them or something.
