What is a tonka bean?

A tonka bean is the seed of the Dipteryx odorata tree, native to Central and South America. It has a distinctive aroma reminiscent of vanilla, almonds, and spices, making it popular in perfumery and culinary applications, often used to flavor desserts and beverages. Tonka beans contain a compound called coumarin, which has anticoagulant properties and is regulated in some countries due to potential health risks when consumed in large amounts.
