i think when you call it pickled or when you call it fermented really isn't such a big difference/deal but i personally am calling all my stuff fermented.
one big problem with this stuff is that if you look at english-speaking cultures, none of them do any of this anymore. they DON'T ferment foods. the only real fermented foods we "all" eat that i can think of is sauerkraut, pickles or soy sauce and then we probably buy it at the store where it's not much good anyway.
so when you search online in english you can hardly find any info on how to do it (unless it's from people from other countries) and 99% of them are saying "wow i thought this was so gross and impossible so i didn't do it for a long time!" as well as "it can be SO DANGEROUS, sterilize EVERYTHING SUPER WELL, wear gloves" etc (protip: no one in the world sterilizes anywhere near as much as americans do, it's completely unnecessary) or you find a lot of wrong/bad info. oh and they all say to do stuff like "you need to put in this and that and tons of sugar", no you don't need that either...
like, i search for fermenting meat and all i can find is how to make sausage, apparently no one's fermenting fish despite that fermented fish is probably the most-fermented meat in the world... or just now i was searching for how to tell if fermented fish for fish sauce is bad, and if tomato sauce is supposed to separate when fermenting (couldn't find an answer to either!) and found a site full of absolutely wrong info (one of those "raw food" sites claiming fermented foods are LESS healthy than "raw" foods - most fermented foods actually haven't been cooked btw... luckily the comments are full of shocked people giving the correct info, but i bet a lot of people don't even read comments)
meanwhile if i search in swedish i find a ton of people talking about/showing pictures of how they're fermenting stuff in their garages and whatnot but usually no real instructions, and if i search in japanese i find instructions super fast (buuut i can't exactly understand them perfectly). this kind of stuff makes me mad because people are always going "i want to learn english, it must have the best / most info" uhh definitely not. maybe, possibly for science and technology but certainly not for any subject that requires "making" stuff such as sewing, cooking, woodworking.... and nothing that requires cultural accuracy in any way (english doesn't even have correct info on vikings. or on modern-day countries).
no subject
