Zengcheng’s late choy sum, also known as tall-legged choy sum, and is a variety of Guangdong choy sum. Because it’s grown and harvested in winter, it often doesn’t reach market until late winter, later than other choy sums, earning it the name. Zengcheng choy sum is known as the ” King of Choy Sums ” and the “Crown of Vegetables . ” Zengcheng’s late choy sum boasts a long growth cycle, crisp skin, tender flesh, and a unique, sweet flavor, earning it a high reputation among diners. Because a typical choy sum weighs no more than 50 grams, each late choy sum can weigh up to 500 grams, earning it the nickname “choy tree” in Guangzhou. When it was first introduced to Guangzhou in the 1980s, many residents didn’t recognize it, believing it was old and brought to the provincial capital by farmers who couldn’t eat it anymore. Consequently, they called it “choy tree,” and few bought it. In reality, despite its tall and large size, the late choy sum is remarkably tender, with a crispy, sweet, and refreshing taste. The lower part of the choy sum, with its thicker diameter can be sliced horizontally for stir-frying with meat.
