e/French butter dish

Information
has gloss	eng: A French butter dish is a container used to keep butter fresh and soft without refrigeration. This late 19th century French-designed pottery crock has two parts: a base with a hollow cylinder attached to it, and a cup that also serves as a lid. The cup holds the packed in butter, and the base holds water. The water creates an airtight seal that keeps oxygen away from the butter so that refrigeration is not needed, and the butter can be used in its soft form. This method will keep butter for around a month provided it is kept at temperatures below 80F (27C).
