Soft butter, every morning.
A water-seal keeper is simple — but a few small habits keep your butter perfectly spreadable for weeks.
Make sure the lid is completely dry before packing butter — moisture causes slipping. Use slightly cool room-temperature butter and pack up to 117 g firmly into the cup.
Pour cold filtered water up to the indicated line in the jar. Insert the butter-filled lid — the water forms an airtight seal that keeps butter fresh without refrigeration.
Lift the lid, spread, return. Butter is hydrophobic, so it won't mix with water if it touches. Keep a paper towel nearby to catch drips when lifting.
Refresh the water every 3 days to keep butter tasting clean. Use the included pendant with a glass marker or sticker as a reminder for your last refill.
