I'm actually interested in trying these! There is no way to say this without some kind of double entendre, but I like to suck on things to keep my mouth occupied sometimes. I get tired of sucking on sweet things so, if these are tasty, they might be a nice change of pace!
When I was a (weird) kid, I would suck on the chicken-flavored bouillon cubes. "Weird kid" me would probably have asked for those at the store. Weird adult me will just make soup.
I still sometimes eat a pinch of dry buillon. Though IDK if I'd like the same thing diluted and long-lasting, the intensity of the dry stuff is part of the draw for me.
