Almonds

Cyanide tastes like almonds. Actually, it’s the other way around. Almonds taste like cyanide, to an extent at least. Almonds contain so much of it that it gives them their typical taste and aroma. But don't worry. You would have to eat 5 kilograms at once to actually have any consequences. Also, the reason we know what cyanide tastes like is because an Indian man named MP Prasad who committed suicide left a hastily scrawled note describing the taste. “Doctors, potassium cyanide. I have tasted it. It burns the tongue and tastes acrid,” he wrote, solving a long unanswered question.
