With it's unique design the French butter keeper keeps butter at the perfect spreading consistency by reflecting outside heat while insulating and cooling the butter: Pack softened butter firmly into the bell-shaped lid, pour fresh water into the base of the crock and place the lid upside down back into the base of the crock. Soft, spreadable butter may be enjoyed and served right from the crock. Inspired by an age-old French tradition, the French butter keeper keeps your butter airtight, thus protecting freshness and flavour. - High fired vitrified porcelain - Contains no lead - Height: 12 cm (4.5 in) - Width: 11.5 cm (4.25 in) - Dishwasher, conventional oven and microwave safe - Handmade and hand painted in Canada (Montreal, Quebec).
