I looked at a few, all were soaked in corn syrup. Finally, I asked the proprietor for beef jerky that didn't have added sugar. She was taken aback, apparently nobody had ever asked her that before. She thought for a minute, and said sorry, not a single variety of beef jerky was unsweetened.
I sadly left without buying any. I remember eating beef jerky in the 1960s and it didn't taste like candy.
P.S. I looked and looked on Amazon for protein powder that was not sweetened. Couldn't find any. If I wanted sugar in it, I'm perfectly capable of adding some myself. I wound up going to a supplement specialty shop, which did have what I wanted.
P.P.S. I was curious what unsweetened chocolate tasted like. I finally found some on Amazon, it's called cacao nibs. It's now my preferred chocolate!
