A thumb-size pod from a plant native to Brazil, said to smell of vanilla with strong hints of cinnamon, cloves and almonds, itâ€(tm)s cheaper than vanilla pods, and sometimes used as a vanilla substitute outside of the United States.
The tonka bean is the seed of Dipteryx odorata, a legume tree in the neotropics, of the Fabaceae family. The seed is black and wrinkled in appearance, with a smooth brown interior. It is known mostly for its fragrance, which is reminiscent of vanilla, almonds, cinnamon, and cloves: it has sometimes been used commercially as a substitute for vanilla.
