Any chinense that I've tried pickling so far has been really good, and as far as my experience with them, it looks like pubescens are great pickled as well. I think pickled scotch bonnet peppers are a gateway for anyone who is on the fence about spicy foods, and I found that Ecuadorian Red Pepper from Hell is absolutely insane when pickled. Both of them are just exceptional on pizza, rice dishes, etc. Before I found out I was allergic to eggs, it got to the point where I couldn't eat scrambled eggs without pickled peppers in them.
Next season (2026) I want to do a baccatum trial, and will likely be pickling some of those as well so I'll look forward to having more to report!
@The Hot Pepper what about you? Anything you like besides jalapenos?
