Brazil nuts, like almonds, are more edible seeds and less nuts. Found in pods that contain anywhere. 

Brazil nut is technically a seed rather than a nut. Brazil nuts taste rich and creamy, and their meat is similar in texture to coconut. Alternatively, they can used as a nutritious topping for oatmeal, salads, or even brownies. Store it in an airtight container in a cool, dry place at room temperature. They are also known to have useful amounts of phosphorous and magnesium.
