Tatsoi mustard is a leafy green vegetable known for its mild, slightly sweet flavor with a hint of mustard. It's often used in salads, stir-fries, and soups. The leaves are dark green and spoon-shaped, growing in a rosette pattern. Tatsoi is rich in vitamins A, C, and K, making it a nutritious choice for health-conscious eaters. It's also appreciated for its tender texture, which holds up well in cooking without becoming too soft.
Tatsoi, or Brassica rapa, originated in China and has been cultivated there for centuries. It's part of the Brassica family, which includes other mustards and cabbages. The vegetable was brought to Japan, where it's known as "tah tsoi," meaning "broad vegetable." Tatsoi gained popularity in Western countries in the late 20th century, appreciated for its hardiness and flavor. It's now grown in various parts of the world, valued in both traditional Asian cuisines and modern fusion dishes.
