To our surprise there is an item readily available on Amazon.ca that will solve the problem. It's called a "Butter Bell". There are numerous designs that will suit almost any decor. We purchased the Norpro White Marble Butter Bell.

Butter bells are designed as a countertop or table storage container where you place your butter to keep it dry, fresh, and free from spoilage. It maintains your butter’s ready-to-spread texture for a month or so, without refrigeration.

Butter bells are not inexpensive but both Loraine and I believe that they are worth the expense.
