Central News Agency reporter Yang Szu-jui, Tainan, April 26:
Tainan has experienced less rainfall since last winter, but continuous frontal rain in April has revitalized many wild plants. Black nightshade, known as "烏甜仔菜" (black sweet vegetable), has also emerged. It may look like an ordinary weed, but it is an old-fashioned rural delicacy.
Huang Yi-bin, head of the Qijiawu Street Flower Production and Marketing Class in Guiren District, Tainan City, told the Central News Agency that after black nightshade flowers and bears fruit, it produces small purple-black berries. In Taiwanese Hokkien, it's called "烏甜仔菜" or "烏籽菜." While unfamiliar to urban residents, for older generations or those living in more rural areas, foraging for some in the wild or along fields means an extra dish on the table; it's a daily ingredient.
Huang Yi-bin said that although recent rains haven't amounted to much, wild plants have been moisturized. Many field ridges, vacant lots, and even residents' vegetable gardens and balcony potted plants have thriving black nightshade. Sometimes, people who know its value are seen "harvesting" it, perhaps to supplement their own meals or sell at local markets.
He stated that black nightshade is classified as a weed and has no economic cultivation value. Although many kinds of vegetables are available on the market, black nightshade has a slightly bitter taste, which might not make it a first choice for younger generations. However, many rural residents still have the habit of incorporating black nightshade into their dishes. For example, his family often has black nightshade porridge, or they simply blanch it and mix it with garlic soy sauce, which brings a "taste of home."
Tsai Chia-ling, manager of Dakeng Leisure Farm, said that the black nightshade harvested from their farm is used to make wild vegetable and seafood porridge, or stir-fried with ginger and sesame oil, and these have always been popular dishes at the farm's restaurant. For people who moved from rural areas to cities, it's a nostalgic taste of home, and many young people also "become loyal customers after trying it once," later even specifically requesting the dish.
Tsai Chia-ling mentioned that although black nightshade is a wild vegetable, its nutritional value is not inferior to that of common vegetables, but it's not easily found in urban supermarkets or stores. When it appears in large quantities in the wild, there's a higher chance of finding it sold in suburban markets.
Huang Yi-bin noted that unripe green black nightshade berries are slightly toxic and should not be consumed, but the tender leaves and stems are safe to eat. Besides common rural areas, it's also a common ingredient among many indigenous tribes. However, when foraging in the wild, one should be careful about whether herbicides have been sprayed nearby to avoid consuming pesticide residues.
He suggested that gardening enthusiasts might try growing it, though typical garden stores might not sell the plants. If black nightshade berries can be obtained, crush their outer membrane in a water-filled container, filter out the water with a paper towel to collect the seeds, then sprinkle them on potting soil. With timely watering, they will grow well, allowing for home harvesting of wild vegetables.
