Peel and dice your apples, making sure all pieces are small in size.
Cook apples down in a saucepan with the butter, salt, sugar, and cinnamon. While cooking the apples, bring your frying oil to temperature (350 degrees).
Once cooked let the apple mixture cool so that you can work with it.
Fill the eggroll wrappers with the apple mixture, but make sure not to fill them too much or the mixture will leak out while frying.
Use water to wet the edged of the eggroll as you close it, this will seal the eggroll shut.
Fry the eggrolls for two to three minutes each, making sure to turn them on all sides. This will ensure you get browning on all sides.
Remove the eggrolls from the oil and let cool.
