Peel them by hand for a delicious and nutritious snack (or don’t bother to peel them – it’s just a little extra fiber!). These roasted cacao beans do not contain caffeine but they do contain theobromine which is a gentle stimulant. These beans were grown in the Moho River Valley of Belize, which is in the heart of the former Mayan Empire. Cacao has been cultivated here for thousands of years. This is the birthplace of chocolate.
