A classic French solution for keeping butter fresh, Butter Bells seem to be one of those items you've either known about forever or have never seen before. The clever ceramic crock keeps spreadable butter fresh on your counter for up to thirty days. The ceramic bell is packed with softened butter, while the crock is filled with cold water. When the lid is placed on the crock, the water creates an air-tight seal that protects and insulates your butter. From then on you need only change the water every few days. Proof that traditional solutions still have their place in the kitchen, Butter Bells make silky smooth sandwiches and toast. Available online from Lakeland, the Butter Bell is £17.99.
