Tiger nuts, also known as chufa, are small tubers that grow underground and are not actually nuts. They are native to Africa and the Mediterranean region and have been consumed for thousands of years. Tiger nuts are rich in fiber, vitamins, and minerals, making them a nutritious snack option. These tubers have a slightly sweet, nutty flavor and can be eaten raw, roasted, or ground into flour. They are often used to make horchata, a traditional Spanish drink. Tiger nuts are also popular among those following gluten-free or paleo diets due to their natural, wholesome properties.
