Our version of a counter top butter keeper is a sturdy cylinder nesting in a larger cylinder. The lid doubles as a base, resting solidly on your counter when in use. You'll only need to use about 1/2 cup of water to keep butter sealed. Keeping butter available in one of these is a treat. At Grateful Dad Pottery we test every item that eventually gets to the store. This is one of our current favorites, getting almost daily use. Surprisingly, butter stays firm and cool on the counter (what we've observed). Measuring about 4" W by 4.5" H these hold about 1 cup of butter.
