This very French butter keeper went viral on TikTok - this is your chance to nab one.
Fill the cup with butter, and add a little salted water to the reservoir. Place the buttercup into the reservior, and the water creates a seal, keeping the butter perfectly spreadable, and preventing it from going rancid.
