Scones are best enjoyed the day of your purchase, but they can be stored in an airtight container at room temperature for 2-3 days. If you keep them longer than one day, refresh them in a 325 F oven for 5 minutes. Let the toasty warm scone is brighten your day.
You can freeze them for later enjoyment, as soon as you can lock in the freshness, placed them in Zip Lock freezer bag or freezer safe sealed container, for up to couple of weeks and reheat them in 325 F for 15 minutes.
All toaster ovens and microwave are notoriously different. You will need to check the scone for the first few times to fine tune the best result.
