I had a request to make a couple of Butter Bells and I have never attempted these before, not too bad for a first attempt.
The idea is for cool climates, so you can keep your butter on the table and it stays soft.
The method is to place salty water in the base and change it regularly to keep the butter fresh.
Add the butter to the V section of lid and when inverted, it sits just above the inside base.
When you take the lid off, the handle sits on the table with the V pointing up for easy access to the butter.
