These are best served immediately. If you need to make them ahead, you can assemble the wontons and refrigerate them for up to 2 hours before frying. For extra flavor, consider adding a pinch of cinnamon or nutmeg to the cream cheese mixture. To avoid oil splatter, make sure the wonton wrappers are not overly wet before frying. Don’t overcrowd the fryer, as this will lower the oil temperature and result in soggy wontons.
