Pepper-only jellies usually have so much pectin I don't like the consistency. They can be like a solid block you take gel like chunks off with a fork. I like jam/marmalade much better because the "jelly" is fruit, not added pectin to make it gel. However a chinense-only is possible and I looked up a good one I've had that is not like that. Angel's Fire Habanero Jelly. Okay seems their base is sweet peppers and sugar and they use habanero powder. So basically instead of using habs as the base and making it inedible they choose sweet peppers and hab powder, lots of sugar, way less pectin, citric acid, and butter. And it's really good! So hope this helps.
I've had stuff so horrible it's like little pepper bits preserved in unflavored pectin gel, so bad.
