Good Gadget: Melissa Clark's Butter Keeper

Butter keepers are intriguing. The ads in the back pages of cooking magazines claim they're an almost miraculous way to keep butter fresh and spreadably soft all the time, but are they really that special? After reading Melissa Clark's recent blog post about her pretty marble butter keeper, we're convinced — they just might be the best thing since sliced bread.

Clark says the first time she saw a butter keeper was in the kitchen of Paula Deen — how appropriate! — and it was intriguing enough to send her on a Google hunt that led to her own lovely marble specimen.

To use it, she fills the egg-cup-shaped top with softened butter and the base with water. The top is overturned into the base, and the water creates a vacuum seal, keeping the butter cool and fresh for up to 30 days, more than enough time to eat a stick's worth of "soft, silky, luscious, spreadable" butter.
