So stone fruit pits I've been told taste a lot like almonds. I've been told that you can make an extract, much like almond extract, out of them as well. I've also heard that stone fruit pits contain cyanide. Reading about this a bit more closely it seems that they actually contain something called amygdalin which contains cyanide and can be released into the body when injested. Pub chem lists amygdala as "slightly soluble in alcohol" but I'm not exactly sure what that means. It leads me to believe that making an extract out of stonepit fruits might be dangerous. However I've seen other culinary sources claiming its safe like this one: https://food52.com/blog/10809-how-to-use-stone-fruit-pits. I'm more inclined to play it safe than trust such a thing.
Is there a trustworthy source that says this is safe? Is there a trustworthy source that says this isn't safe?
