Totsoi

Totsoi (Brassica rapa var. rosularis) is a Chinese mustard green with a mild peppery flavor. Its leaves can be eaten raw or cooked. The leaves are tougher and stronger flavored than standard pak choy and hence many prefer it cooked (stir-fried, steamed or in soups) rather than raw. Young leaves can be used in salad.

Cooking

Many Chinese and Japanese recipes use mustard greens, including Totsoi and Mizuna. Asian mustard greens are generally stir-fried or pickled. A South-East Asian dish called asam gai choy or kiam chai boey is often made with leftovers from a large meal. It involves stewing mustard greens with tamarind, dried chillies and leftover meaton the bone.
