TheKilner Glass Butter Belloffers a traditional yet clever solution for keeping butter fresh and soft at room temperature. With a 200ml capacity, it’s perfect for storing standard-sized blocks of butter in a way that keeps them ready to spread—without refrigeration.
How it works:
Pack softened butter into the bell-shaped lid, press firmly to eliminate air pockets, and fill the base with 70ml of cold water. The water creates an airtight seal that keeps butter fresh for up to a week. Simply change the water every 2–3 days.
