Brazil nuts are large seeds from the Bertholletia excelsa tree, native to the Amazon rainforest in South America. They are known for their rich, creamy texture and high nutritional value, being an excellent source of healthy fats, protein, and essential minerals like selenium. These nuts are typically found in hard, woody capsules that can weigh up to 2.5 pounds. Harvesting involves collecting the fallen capsules and cracking them open to extract the seeds. Brazil nuts are often enjoyed raw, roasted, or as an ingredient in various dishes, providing a unique flavor and numerous health benefits.
