The Tonka bean, also known as tonka bean, tonka bean, tonka, coumarouna, tonquin, tonqua, Coumarrouna odorata or Baryosma tongo, is a tree found in South America. It is native to Guayanas, Venezuela, but is widespread throughout tropical America from Central America to Brazil. It is mainly found in rainforests, where it grows to a height of 25 to 30 metres. It is mainly used for its seeds, which at first sight resemble small beans.

These seeds, often referred to as tonka beans, are an important raw material in food and perfumery. When dried and after the skin is removed, they give off a strong vanilla scent with hints of cinnamon, almonds and sprouts. This strong and unique scent is used in perfumery, where they are used in some luxury perfumes and home fragrances. Tonka beans are also very popular in gastronomy where they are used as a spice. In Europe, they are mainly used in bakery and confectionery, where they enhance the flavour of pastries, ice cream or puddings. They can also be found in some special recipes for mixed drinks, where they add an interesting flavour dimension to cocktails.
