Rakkyo (Allium chinense), also known as Chinese Scallion or Jiao Tou, is a small-bulbed perennial Allium species cultivated across East and Southeast Asia for its crisp, sweet-tart bulbs that are almost exclusively consumed as pickles. The glossy, dark purple to reddish-purple bulbs have a unique firm-crisp texture and mild onion-garlic flavor that makes them one of the most prized pickled vegetables in Japanese and Chinese cuisine.
• The species epithet "chinense" means "Chinese," referencing its East Asian origin
• In Japan, pickled rakkyo ("rakkyozuke") is the traditional accompaniment to curry rice — as beloved as pickled ginger is to sushi
• The bulbs have a remarkably crisp, almost apple-like texture even after pickling
• Rarely eaten fresh — the bulbs are almost always pickled, sweetened, or preserved
• One of the few Allium species that is valued primarily as a condiment rather than a cooking ingredient
• Grown in China, Japan, Korea, Vietnam, and Thailand for centuries
• An important condiment in Japanese cuisine since at least the Edo period (1603–1868)
• Chinese cultivation dates back over 2,000 years
• The plant is mentioned in classical Chinese agricultural texts
• Introduced to Europe and North America as a garden curiosity in the 19th century
• Remains little-known outside East and Southeast Asian culinary traditions
• Widely commercially cultivated in Japan, particularly in the Tottori and Kagoshima prefectures
Bulbs:
• Small, ovoid to globose, 1.5 to 3 cm in diameter
• Growing in tight clusters of 5 to 20 bulbs
• Outer skin thin, glossy, dark purple to reddish-purple
• Inner flesh white, firm, crisp, and juicy
• Mild, slightly sweet onion-garlic flavor
Leaves:
• Hollow, tubular, 2 to 4 mm in diameter and 20 to 40 cm long
• Dark green, growing in a clump from the bulb cluster
Flower stalk:
• Slender, 30 to 60 cm tall
Flowers:
• Small, bell-shaped, pale purple to violet
• Borne in a loose umbel
• Often sterile — commercial propagation is almost entirely vegetative (by bulb division)
Roots:
• Fibrous, shallow, white
• Good source of dietary fiber
• Contains vitamin C and vitamin B6
• Provides minerals including calcium, phosphorus, and potassium
• Contains allicin and other organosulfur compounds with potential cardiovascular benefits
• Rich in fructans — prebiotic carbohydrates that support gut health
• Pickled rakkyo retains some vitamin C and provides beneficial fermentation byproducts
• Approximately 60 to 80 kcal per 100 g of fresh bulbs
Planting:
• Plant individual bulbs 3 to 5 cm deep and 10 to 15 cm apart
• Rows spaced 30 to 40 cm apart
• Autumn planting is traditional in Japan for summer harvest
Site:
• Well-drained, fertile soil with pH 5.5 to 7.0
• Full sun to partial shade
• Requires consistent moisture during active growth
Care:
• Keep soil moist but not waterlogged
• Side-dress with compost during the growing season
• Remove flower stalks to direct energy into bulb growth
Harvest:
• Harvest when leaves begin to yellow and die back, typically June to July
• Lift bulb clusters carefully
• Cure in a warm, dry place for 1 to 2 weeks
• Bulbs can be stored for several months in cool, dry conditions
• Pickled in sweet vinegar (amazu rakkyo) — the classic Japanese preparation, served with curry rice
• Pickled in soy sauce and sugar (shoyu rakkyo) — a savory-sweet condiment
• Sweet pickled in sugar and vinegar — popular in Chinese cuisine
• Occasionally stir-fried with other vegetables
• Added to noodle dishes and rice bowls as a garnish
• Used as a palate cleanser between dishes
• In Vietnamese cuisine, added to noodle soups and stir-fries
Other uses:
• The crisp texture makes it a unique addition to relish trays
• Can be used as a cocktail garnish (like a pickled onion)
재미있는 사실
In Japan, rakkyo pickles are to curry rice what pickled ginger is to sushi — an absolutely essential accompaniment. Japanese convenience stores sell small packets of sweet-pickled rakkyo alongside their curry rice, and the average Japanese person eats about 200 grams of rakkyo pickles per year.
