The unique design of the French Butter Dish keeps butter at the perfect spreading consistency.  The water creates an airtight seal  that keeps oxygen away from the butter (oxygen is what turns butter rancid).  In the bell shaped lid your butter will stay soft and fresh! When you want to serve the butter, the top part rests securely on the table. To use a French Butter Dish, "pack"  1/4 to 1/2 pound of butter into its bell or cone-shaped lid, then put water into the base so that it is about 1/3 full (use salted water for unsalted or low-salt butter). When the inverted bell shaped lid is on, a seal is created that keeps oxygen away from the butter. Your Butter will stay soft and fresh!   When you want to serve the butter, the top part rests securely on the table. Put a small amount of salt in the water to stop mold. Change water at least once a week.
