The culinary multitalent, also known as bread nut, grows in Guatemala and other places, and has a lot of fans. Julio Madrid is one of them.

About "My favorite"

With all the talk of endangered species, the value of biodiversity and the usefulness of ecosystems, we sometimes forget why plants and animals are really worth protecting: because we love them, or depend on them for our own wellbeing. People from all walks of life and in all parts of the world have a favorite species. The reasons are many - perhaps because it is beautiful, or fascinating, or it helps them secure a livelihood. Meet some of these people and their favorites in our series "My favorite."
