Ensure oil temperature is around 350°F (175°C) for best frying results. Avoid overmixing batter to keep fritters light. Use light beer for crispness or substitute with sparkling water for a non-alcoholic version. Add optional ingredients like cornmeal for extra crunch or herbs and spices for flavor variations. Leftovers can be refrigerated for 2 days or frozen uncooked; reheat in oven to maintain crispiness.
