Butter your toast, biscuits, and muffins with ease using our white Hummingbird Butter Crock. Made from high quality glazed porcelain the crock keeps butter soft, fresh, and spreadable for up to one month. Fill the top of the butter crock with 1 stick of butter (1/2 Cup Butter) and the base with 1/2 Cup of Water. When the top of the butter crock is place onto the base the water creates an airtight seal keeping your butter fresh for up to 1 month (change water every 2-3 days to keep fresh). Food and dishwasher safe.
