Never understood this. I dick around while baking all the time. I pretty much never follow the recipe, and just throw whatever in in whatever amount I feel like. Sometimes things get weird, but usually it turns out alright with just a bit of extra flour or water to get the consistency right.
Cooking on the other hand… As far as I can tell, meat goes from raw to tough as nails in about 3 seconds.
I mean, antiligature hardware is a thing, and is usually required by law for psychiatric facilities, at least in the US. Not saying this isn’t true, just saying that it’s not unusual for a place claiming to be for psychiatric care to employ standard care for psych patients.
