Brazilian coquitos, or Brazil nuts, are the fruits of the Amazon chestnut tree, a majestic tree that can reach up to 50 meters and live for up to 1000 years. Known for their sweet, coconut-like flavor, these nuts are perfect as a snack or a delicious addition to cakes and cookies. Their high selenium content makes them nutritious, but it's important to consume them in moderation to avoid exceeding the recommended dose.
