The proper way to store butter is in a butter dish [0], not a refrigerator. At room temperature you'll have no issues spreading it. It'll go rancid after a week or so, so if you don't use it everyday then this obviously isn't a good option. In Britain toast is more popular than cereal for breakfast.
