We have a French butter keeper. It uses water for as an airlock to keep the butter fresh on the counter at room temps. Unfortunately, we can't use it now because our Lab Retriever eats anything and jump up on our counters.
If you've never seen one, check it out.
That reminds me of our wonderful Newfoundland, Lady. My mother had just put a 1LB brick of butter on a butter dish that was placed in the middle of the kitchen table. I don't remember all the details,
as it was over 60 years ago.
We had left the room, came back and found the butter dish exactly where my mother had put it. Just the dish, no butter. The dish was clean as a whistle and nothing in the surrounding area had been
disturbed. As I recall, we had left the room for a very short time.. Lady acted normal as if nothing had happened.
