What are tonka beans?

Tonka beans are black wrinkled beans with a soft brown interior that holds the seeds inside. The pods need to be cracked to reveal the fruit. Then the seeds need to be removed from the fruit, soaked and dried so the aroma can be released.

The tonka seed is high in coumarin, a chemical isolate from this plant, which gives tonka bean this pleasant odor and a popular ingredient in the perfume industry!
