Does the water touch the butter in a butter bell?
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.
How long will butter last in a butter bell?
Why do you put water in a butter bell?
Then you add an inch or so of water to the crock half, and replace the butter filled lid. The principle is that the water seal keeps germs and goobers out of your butter, the air pocket keeps your butter dry, and the whole contraption maintains itself close to room temperature and is great for spreading.
How often should you change the water in a butter bell?
Make sure you change the water every 3 days.
