Mini Butter Keeper (Set of 4)

These ceramic devices are used to keep butter fresh without refrigeration for up to a month. They work by protecting the butter from the air with a water lock seal. Clean water is placed in the base while the butter is pressed into the bell or cup. The bell is then turned up-side-down into the base dish. If the temperature in your kitchen remains below 75 degrees F, there is no need to refrigerate the butter.
