Hadn't seen this before - I wonder if that was once on the potato outside and then grew closed?
This is referred to as hollow heart.
It usually indicates as shortage of available calcium in the plant as the tuber grows. Basically the same thing as blossom end rot in tomatoes, peppers etc.
Some varieties are more prone to developing this than others.
Hot dog! I knew there'd be a juicy explanation in the comments. Way to be my dude.
today I learned :)
The Internal cavities are usually a result of poor growing conditions.
It's just two internal holes that happen to look like a mushroom together. I've had potatoes with one of those holes before.
I believe they are caused by lack of water or just happen sometime.
Here's an example that doesn't look like a mushroom, and had been cooked: https://www.eatortoss.com/whats-up-with-this-freaky-hole-inside-my-baked-potato/
Eat or toss? Eat! As hollow heart can sometimes manifest in surprisingly geometric ways, you might pretend you’re a spy who just received a secret, potato-based message! Or, maybe not.
Haha - I love it.
Don't you just use the stabby end of your potato peeler and core out all the brown spots?
I do. Apparently for those internal growth deficiencies it's not needed, but I still wouldn't wanna eat that :D
It sees you.
Hide-a-shroom.
It happens sometimes with large potatoes.
I doubt it, seeing as all the cavity consists of tapered shapes. A mushroom would leave behind some evidence of being sealed inside, and the mushroom cap structure grows above ground, while spuds grow buried underneath soil. It logistically doesn't quite check out IMO.
What I suspect happens in these kinds of shapes- and I see them fairly often -is that the potato simply expands as it grows, and it just pulls apart at some point of stress, kinda like a warped piece of wood.
Except its an oblate spheroid, so it "cracks" in the center.
This could be some kind of encapsulated material, I don't know the details of how potatoes protect themselves from foreign bodies.
But, in theory, there could be some kinda dead fungus in there, slain by a potato-based void...?
I wasn't saying there was a mushroom inside :) I meant it may have grown with a small pit, which it then grew over / closed the walls on. But the other explanations here are more likely.
Lol sorry, I totally misunderstood. But I'm learning so much about potatoes, so its a cool thread anyway!
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.
