A relative of the red kidney bean, black turtle beans are a legume native to Mexico and are a staple ingredient in many Latin American and Caribbean dishes. Growing black turtle beans is a fairly simple process, as the seeds require minimal attention and do not need fertiliser. Resistant to disease and extreme heat, they’re able to pull nitrogen from the air, which not only helps them to grow but also naturally nourishes the soil around them.
Black turtle beans are a good source of proteins and fiber. They have a low glycemic index. Despite the name, black turtle beans aren’t actually black but a dark purple colour. They have a distinctive small white dot and, like other black bean varieties, they turn brown when cooked for a long time.
