In recent years, Brussels sprouts, known locally as bắp cải tí hon, have made a notable entry into the Vietnamese market, commanding prices as high as 400,000 VND/kg. Originating from Belgium, these mini cabbages are primarily grown for their edible buds and thrive in cool climates found in Europe, North America, and select regions like Dalat in Vietnam.
Historically, Brussels sprouts were cultivated during the French colonial era in Dalat, initially for official use but later fell out of widespread production. Today, they are still mainly grown on a small scale for household consumption rather than commercial purposes.
According to research, mature Brussels sprout plants can reach heights between 80-120 cm and yield approximately 150-170 mini sprouts per plant, weighing around 50-60 sprouts per kilogram. Each sprout is roughly the size of a cherry, with diameters ranging from 2.5 to 4 cm.
Brussels sprouts are ideally suited to cool climates, making them suitable for cultivation during the winter-spring season in Northern, Central, and Central Highlands of Vietnam. In the South, growers must seek out cooler, shaded areas to successfully cultivate this delicate crop.
Despite their high cost and rarity due to complex transportation and stringent cold storage requirements, Brussels sprouts are now available in supermarkets, typically sold in sets weighing between 250-350 grams, priced at over 100,000 VND per set.
Furthermore, Brussels sprouts seeds are increasingly available online, with prices averaging around 100,000 VND for two packets. Ensuring the seeds are from reputable sources and selecting uniformly round, black seeds can significantly improve germination rates.
Brussels sprouts are hailed as a superfood rich in folic acid, vitamin K, vitamin A, fiber, and low in fat, offering numerous health benefits including cholesterol reduction and brain function enhancement, making them a valuable addition to any diet, particularly for combating cancer.
In culinary terms, Brussels sprouts are best when lightly cooked to retain their sweetness and texture, commonly prepared roasted, steamed, or added to salads and soups for their distinct flavor.
Brussels sprouts, with their nutritional richness and unique cultivation requirements, represent both a gourmet delicacy and a health-conscious choice. Their entry into the Vietnamese market underscores a growing appreciation for diverse and nutritious vegetables.
