Sacha inchi, the Inca peanut, is native to the Caribbean and parts of South America. This plant grows large, unique-looking green fruits with six points that are cultivated for their large seeds. People use the seeds in multiple ways. One of the most common ways of preparing sacha inchi seed is roasting and eating it, though it can also be ground into a powder and added to various dishes. You can also extract the oil from the seed and use it for cooking or for the skin and hair.
