Witmer Company Peanut Butter Mixer
I only buy peanut butter of the all-natural variety, meaning the only ingredients are roasted peanuts and salt. The stuff is delicious, but it separates in the jar and it can be a pain (sometimes even a mess) to stir it back together.
That is, until I discovered this peanut butter mixer. It’s a curved mixing rod that pokes through a “lid” and attaches directly onto a standard-sized peanut butter jar. The process is easy: assemble the mixer, turn the crank until everything is mixed well, then pull the mixing rod out of the lid clean. You can watch the process in this video.
