Brassica Rapa Subsp. Chinensis
Bok choy (Brassica rapa subsp. chinensis) is a leafy green vegetable from the cabbage family (Brassicaceae), commonly used in Asian cuisine. It has crisp white stalks and dark green leaves with a mild, slightly peppery flavor
History
Bok choy (Brassica rapa subsp. chinensis) has been cultivated in China for over 1,500 years and is a staple in Asian cuisine. It originated in the Yangtze River Delta and was first grown for medicinal and culinary purposes during the Tang Dynasty (618–907 AD).
During the Ming Dynasty (1368–1644 AD), bok choy became widely popular in Chinese agriculture and spread to Korea and Japan. European traders and Chinese immigrants later introduced it to North America in the 19th century, particularly during the California Gold Rush, when Chinese laborers brought it as part of their traditional diet.
Today, bok choy is grown worldwide and is valued for its nutritional benefits, mild flavor, and versatility in cooking.
Nutrition
Bok choy is low in calories (13 kcal per 100g) but rich invitamins A, C, K, folate, calcium, and potassium. It supports immunity, bone health, and digestion, making it a nutrient-dense addition to any diet.
Season
Bok choy is a cool-season crop grown in spring and fall, thriving at 55–75°F (13–24°C). It matures in 30–60 days, with baby bok choy ready in 30–40 days and full-sized heads in 50–60 days. Harvest before extreme heat or frost for the best quality.
Selection
Choose firm, crisp stalkswithvibrant green leaves and no wilting or blemishes. Smaller heads are tender and sweet, whileheavier ones indicate freshness. Avoid slimy or dry bok choy.
Storage
Store unwashed bok choy in a plastic bag in the crisper drawer of the refrigerator for up to a week. For longer storage, blanch and freeze in an airtight container. Keep bok choy dry to prevent spoilage.
Trimming and Cleaning
Rinse bok choy under cold water, cut off the base, and separate the stalks. Soak in water to remove dirt, then rinse again. Trim damaged ends and cut to desired size.
Stir-Frying and Sautéing
Heat oil in a pan over medium-high heat, add garlic or seasonings, then cook chopped bok choy for 3–5 minutes, stirring frequently. Cook stalks first, then add leaves for even cooking. Season and serve hot.
Baking and Roasting
Toss chopped bok choy with oil, salt, and pepper, then spread in a single layer on a baking sheet. Bake at 400°F (200°C) for 12–15 minutes or roast at 425°F (220°C) for 8–12 minutes until tender and slightly crispy.
Grilling
Brush bok choy with oil, salt, and pepper, then place on a preheated grill (medium-high heat, 400°F/200°C). Grill for 3–5 minutes per side until tender and slightly charred. Serve with lemon juice or sauce.
Microwaving
Place bok choy in a microwave-safe dish with 2–3 tbsp. of water. Cover with a lid or damp paper towel and microwave on high for 2–4 minutes until tender. Drain excess water, season, and serve.
