After many requests for French Butter Crocks, we found some that we are proud to offer to Peter Pots customers. French Butter Crocks let you keep butter fresh and soft for up to three weeks without refrigeration. Fill the bell with a half cup of butter (one full stick), and the crock with 1/3 cup cool water. The butter is sealed, inverted in the water, and stays soft. Change the water every three days. This is the authentic and original design, in glossy off-white glaze with dark blue banding, brilliant white, or off-white matte . 4” diameter and 4” height.
