At my job there this almond flavored coffee pods that when brewed smelled overwhelmingly almond-y. My cousin works in metal reclamation an they work with a LOT of cyanide, I tell him if he ever wants the day off, I'll get him a pod, all he needs to do is spill that coffee and they'd shut down the entire floor to double check things.
(context if you're lost is that cyanide smells a lot like almonds)
