This peanut butter contains chili powder, cayenne pepper, crushed red pepper, and paprika, among other ingredients. I was surprised to see vinegar listed.
It was incredibly tasty, but I was also surprised to see that it was actually very hot. They didn't just mix in a little heat, this stuff is really hot.
On their website this goes for $6 a jar, but I find it in stores for $3.39 or so. Not a bad price and I'm ready to buy more.
I haven't tried their other flavors, but intend to: Mighty Maple, Cinnamon Raisin Swirl, and The Bee's Knees are just some of the others.
