The deadly tonka bean (often added to perfume as a cheap alternative to vanilla) is banned outright in the United States as a food additive. Despite its highly poisonous qualities, it is popularly enjoyed in France in high quality pastries (pictured above is Jean Paul Hévin’s famous “Tonka”). Despite its reputation as a killer, only a few countries ban its use in food. The smell of fresh tonka beans is like a combination of bitter almond, vanilla and clove. It is unique in its mix of tastes, which is why it is so highly prized in the best European pasty houses.
