So I'm watching Unwrapped, all the while remembering the late great Double Dare.
Inbetween segments on how Nutella was made[note: their spokesman until some Denver...Unpleasantness? Kobe Bryant] and some restaurant that made over 100 different types of peanut butter, was this item:

According to the company, you can keep a whole stick of butter fresh and spreadable for up to a month without having to put it in the fridge. Also, these have been around for about 200 years.
