I would love to have something on my dinner table but afraid to use them without refigeration. How in the world it would keep butter fresh in that crockpot? I know they put water inside of it but can not figure how water affects anything. If water is warm it would melt butter, turning it rancid. I certainly dont want anyone sick either! I would love to use butter on reenactments, sitting out in the 80 to 90 degree weather does not sound good and it would be a great save spacer and table serving anyone wants butter on bread and so forth. Has anyone use it? Pros and cons! Any good manufactors I can buy?????????
