How to Store or Freeze This Dessert
Allow the Japanese sweet potato dessert to cool completely before storing. This prevents condensation, which can make the dessert soggy.
Transfer the cooled dessert into an airtight container. For best results, use a container that fits the amount of dessert closely to minimize air exposure.
Store the container in the refrigerator if you plan to consume the dessert within 3-4 days. The cool temperature will keep the sweet potatoes fresh and maintain their flavor.
For longer storage, consider freezing the dessert. Portion the mashed sweet potatoes into individual servings before placing them in freezer-safe bags or containers. This makes it easier to thaw only what you need.
Label each container or bag with the date of preparation. This helps you keep track of how long the dessert has been stored and ensures you consume it while it's still at its best quality.
When ready to enjoy, thaw the frozen dessert in the refrigerator overnight. This gradual thawing process helps maintain the texture and flavor of the sweet potatoes.
Reheat the thawed dessert in the microwave or on the stovetop. If using a microwave, heat in short intervals, stirring in between to ensure even warming. On the stovetop, use low heat and stir frequently to prevent sticking.
If the dessert seems a bit dry after reheating, add a small amount of melted butter or honey to restore its creamy texture and enhance the flavor.
