Homemade clotted cream will keep in the refrigerator for up to 5 days in an airtight container. While this recipe is designed for enjoying fresh clotted cream, you can freeze leftovers for up to 3 months if needed. Be aware that freezing may cause a slight change in texture. If you do freeze your clotted cream, let it cool completely first. Transfer it to an airtight container suitable for freezing, label it with the date, and store it in the back of your freezer. When you're ready to enjoy it again, thaw the clotted cream overnight in the refrigerator. Remember, it's best not to refreeze thawed clotted cream. So, for the ultimate taste and texture, enjoy your clotted cream fresh whenever possible!
