Keep your butter blissfully soft with the Kates Butter Dome! Say goodbye to fridge-hard butter and hello to smooth, spreadable goodness. Here’s how it works: Just pour 1/3 cup of cold water into the base, then scoop and pack room-temperature butter snugly into the bell-shaped lid. Flip it over and seal it into the base so the water gently hugs the rim, making sure to keep the water changed out every 2-3 days. That clever little water seal keeps air out and freshness in—so your butter stays soft, tasty, and ready to spread at a moment’s notice.
