Organic 3" Starts. Red Russian kale has a mild, slightly sweet, and nutty flavor with a hint of peppery earthiness. Compared to curly kale, it is much less bitter, making it a great choice for raw salads and slaws. The tender, flat leaves have a soft, almost velvety texture, and their purple-tinged stems add a slight crunch. When cooked, Red Russian kale becomes even sweeter and develops a rich, savory depth, making it excellent for sautés, soups, and braised dishes. Its balanced flavor and tenderness make it one of the most versatile kale varieties.
