That sounds so strange but interesting. I am not sure I am willing to try it but I still like seeing stuff like that. Its just so very different from anything I am familiar with. o.0
I spent several years doing some -=very=- armature brewing but never did a mead. My wife is the one that ferment's food-stuff and it's always good. I should get into that as well.
Lacto fermenting garlic is a simple way to start. Just Google it for the percentage I want to say 2.5% salt to weight of garlic and water. I leave it on the counter until it gets kinda translucent, kinda changes color a bit, and then put it in the fridge. I use it like I would raw garlic. It's milder but I don't have to worry about dry, powdery garlic which happens quickly where I'm at.
Garlic is the one I really use a ton. When I see decent garlic, I buy a bunch and ferment it. I'll try to remember to grab some pictures tomorrow when I check on and stir everything I've got going lol. While my tea water is heating I feed my sourdough starter and poke at any of the ferments that need a poke.
You need to start posting random things like this to one of the "food" subs and not just in comments. We are a recipe website now. We just have other random crap to read next to the real content.
Lol. Next time I make something I will take pics and write it up. I will def do the nukazuke if it's not totally gross. I'm always making something. If I have time tomorrow I'll post a pic and recipe for my key lime/lemon curd. The marmalade I made, I really like. but it's probably too sour for normal people.
