Ensure even cooking by cutting the sweet potatoes into uniform sizes. For an extra kick, add more jerk seasoning or fresh chilies to the mixture. You can experiment with different spices such as cumin or coriander to customize the flavor profile. If you have leftovers, store them in an airtight container in the refrigerator for 3 to 5 days. Reheat in the oven at a low temperature or microwave.
