Thanks for posting this, Mikki! I had never heard of such a device.
I eat almond butter almost every day, and I HATE it when I get into a new jar and have to stir it (if you refrigerate it afterwards, it stays stirred). I had a pretty good technique down, using a long, thin silicone spreader (with a stiff metal core), but I still always ended up with some of it on my hands, and scraping the spreader clean was a hassle. So I jumped on this gadget!
I get my almond butter at Costco (Kirkland Signature), and the jar is a little bigger than the model 400 specs (27-ounce vs. 26-ounce, and 3.5-inch lid vs. 3.25), but I decided to give it a try. Fits fine! It’s easy and quick to use, it did a good job (even on the concrete bottom), and the stirring rod comes out completely clean.
I’m amazed. So happy I got this!
