Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

I quick-picked some green beans and a week later, the garlic in the jar had turned blue green, turquoise, smurf color. I googled it and brought up a reddit thread that said it's safe to eat.

I did not eat it.

Sorry couldn't upload in an edit.

Excerpt from "the art of fermentation". About fermented (not necessarily pickled) garlic.

Oops, not sure how to fix the rotation

Dude, nice source. I rotated and highlighted for the next pickler that has never seen blue garlic before.

This is true! I'm no chemist but I make paint pigments from plants rich in anthocyanins, which give them colour. Popular mordants (things that helps a colour stick to fibre) are copper salts, which can brighten the colour or make it more blue/green.

And, an old kind of pigment, verdigris, was made by hanging pieces of copper in closed containers with vinegar, where the vapour would cause a blue/green/gray salt to form.

When I saw the post thumbnail on my feed and opened the post, I guessed it's some kind of copper reaction. Neat

I've eaten the blue-green garlic before. It's delicious

Trusting a post on reddit is almost as dangerous as trusting AI.

IIRC this is kinda a "There the same picture" sort of situation, since most LLM's lean heavily on Reddit as a source.

[–] ThePantser@sh.itjust.works 2 points 1 week ago

Exactly, and you dont know if someone fucked with their post to "delete" it. Would be a great way to poison AI by editing your posts with wrong info instead of garbage info.

[–] chocrates@piefed.world 5 points 1 week ago

I'm pretty sure that is common in pickled garlic but do some reading on it I guess.

Sometimes it turns blue just sauteing it in butter
