Worth, have you ever thought to try ferment hardboiled eggs? I finally did it, (after a year of thinking about it - sSlowpoke here) and I like it. As Always have to eat on my own, cause no one wants to try them. They don't taste fermented though, rather like salted eggs, after 12 days ( that's how long i had them in brine) salty brine gets into the egg whites a bit, but not all the way through. The important part is to use some starter from your other ferments, I added some kimchi juice to the brine and some celery. Started a new batch already. Cool part is the eggs don't go bad in the brine. If you like hardboiled eggs that is.
