HechoAmano: You learn something disgusting every day around here

UncleJesse: It did at one time apparently: https://food.ndtv.com/news/where-does-vanilla-flavouring-come-from-beaver-extract-viral-news-2414224 ... The good news is that Castoreum is now seldom used in food products, as vanilla flavouring is now made with a substance called vanillin. This is due to the fact that beaver populations started dwindling, along with the high costs of extracting the compound from the animals. So, rest assured, you can use vanilla flavouring while baking without fear!
