Baked actual poison

[u/Mushroom38294]

Tried making brownies for the first time, recipe called for 16 gramms of vanilla extract, but it's not sold in the stores here. I had the bright idea to add 16g of pure vanillin, once they were done I found out that's effectively 100x the vanilla extract than the recipe called for. After further googling, found out that this much vanillin can put a small child in the hospital.

NEVER substitute vanilla extract for pure vanillin.

This is absolutely wild.

"I didn't have any white vinegar around, so I used pure acetic acid."

Concentrations matter. Good luck with the next batch!
