Idle question. I've always heard that you need to prick the skins before baking a potato. The potential consequence for failure to do so is a catastrophic potato explosion.
In the comments, someone said they had potatoes explode after baking, letting them cool for a bit, then re-baking.
Personally, I don't usually bake enough potatoes to justify turning on the oven, so I microwave them; which is notorious for for getting food everywhere without adequate supervision.
I was going to reference the same video, but highlight the part where they said they did a whole bunch of experiments to try to get a potato to explode, but never managed to do it. They specifically asked for anecdotes in the comments to help them figure out what they were doing wrong (or right, if you don't want exploded potatoes).
In other words, they still recommend docking just in case, but apparently exploding potatoes are really really rare (unless you know the trick to make it happen on purpose, I guess).
Despite microwaving potatoes frequently, (1-10/wk, don’t judge me) for many years (often questionably, typically without pricking) I have yet to have one explode. One would assume microwave explosions would be more common.
Perhaps luck, perhaps potato type/size (I like Yukon gold and reds, which are thin skin, small, and relatively soft) but it’s just me so I don’t usually buy large/baking potatoes, and maybe those are more prone to bursting?
I put them in a lidded microwave safe container, bit of water in the bottom, microwave for 10-15 minutes. Never a burst in.. almost 20 years?
Potatoes absolutely will build up enough internal pressure to pop, even if the skins have been punctured. Not every spud will blow up some just split; when they do it makes a hell of a mess in the oven. I once broke a microwave at work with a potato because it did this.
To postulate a reason; some potatoes have a higher moisture content than others.
In the oven, really hot and it blew open and "baked" all over the inside. Hell to clean up. I was sure I poked it, but... couldn't remember.
Now I go all serial killer on them before baking.
I was under the impression it only really happens in the microwave. The oven heats it slower so it might get a crack to let the steam out, but a microwave is so quick it can get a small portion that seems to "explode" enough to get a bit of potato on the inside of the microwave.
When I was a kid my mom was baking potatoes one time and realized partway through that she forgot to stab them before putting them in the oven. She quickly opened the oven and slid the rack out and stabbed one with a fork. Unfortunately it was too late. I was standing right next to the oven and potato exploded all over my mom and I as soon as the fork touched it.
No. But I did have one catch on fire in a big way, because it was already fully cooked (low moisture at that point) and too close to the broiler element. I had never used a broiler before. The starch and sugar in a potato is quite flammable.
