Based on an old French design this two part butter keeper is glazed in greens and white with deep teal detail. It is 7 cm tall and measures just under 11 cms in diameter. Add a little water to the base, pack the butter into the lid and invert into the base. The water forms a seal making sure the butter doesn't go rancid whilst staying perfectly spreadable whatever the weather!
The keeper is dishwasher safe but gentle handwashing is recommended.
