How to choose: Elegant bok choy (Chinese white cabbage) boasts smooth, dark green leaves on crisp white stems. Don't purchase heads with brown specks, indicating age. Refrigerate up to three days.
Preparation tips: Cut stems crosswise into chunks and thinly slice leaves. When cooking, start stems two minutes ahead of leaves. Stir-fry in sesame oil, garlic, and broth; top with poached fish. Or braise and toss with Asian noodles, fresh ginger, and plum sauce. Delicate baby bok choy, a miniature version of its big sister, can be sliced lengthwise and pan-seared with soy sauce, peanut oil, and chopped scallions.
Health benefits: Part of the cabbage family, bok choy provides vitamin C, folate, calcium, and fiber.
