For extra flavor, try adding 1 tablespoon of grated fresh ginger or a squeeze of lime juice to the meatball mixture. If you don't have sambal oelek, you can substitute with sriracha or another chili garlic sauce. To ensure even cooking, use a thermometer to monitor the oil temperature and adjust as needed. These meatballs can be made ahead of time and stored in the refrigerator for up to 24 hours before frying. Serve with your favorite Asian dipping sauce, such as sweet chili sauce, teriyaki sauce, or a simple soy sauce with sesame oil.
