Mizuna is a Japanese mustard green with dandelion-like jagged edge green leaves and a mild, sweet earthy flavor. Mizuna makes an excellent salad green and it’s also used in stir-fries and soups. Use it just like spinach! The tender leaves have a subtle pleasant flavor to them, considerably toned down from the peppery arugula, so if you’re not a fan of arugula with its stronger taste, then mizuna might be your green of choice. When cooked, the deep nutty and slightly bitter flavor gets drawn out, making it a popular dish served with noodles and seafood in Asian cuisine.
