Problem Solving: If your wontons are burnt: Then reduce your heat. If the cream cheese filling leaks into the oil : Then you may have placed too much of the filling into the wontons or it could be possible that your wontons may not have been completely sealed. Also if you cook your wontons for too long it will cause them to open up while cooking. You will need to increase your heat just a bit. It should only take about a minute for the wontons to brown. If it takes longer than that then your heat is not hot enough . If the inside of your wontons end up oily : Then the wontons may not have been completely sealed and have popped open slightly while cooking . The insides of the wonton will also become oily if the oil temperature is too low. If you are frying your wontons for more than a minute then your heat may not be hot enough. You heat should be about Medium-Low to Medium.
