🌱 What it is
Swiss chard is a leafy green in the beet family, known for its glossy dark leaves and bright red, yellow, or white stalks, with an earthy flavor similar to spinach.
📜 Where it comes from
Swiss chard descends from wild beet plants native to the Mediterranean region, where Greco-Roman writers including Aristotle described it as a cultivated leafy green. It became a staple leafy vegetable throughout Mediterranean and Middle Eastern cooking for centuries. Despite its name, it has no particular connection to Switzerland, having gained that label through a nineteenth-century seed catalogue naming convention.
