Green vegetables that are tender can be stir-fried with bamboo shoots. During the summer, dress it with ground mustard and a little vinegar to awaken one’s appetite. One can make a soup with it using dried-cured ham. One must look for those that have been freshly picked to ensure that they will be soft and tender.
青菜1
青菜擇嫩者，筍炒之。夏日芥末拌，加微醋，可以醒胃。加火腿片，可以作湯。亦須現拔者才軟。
Notes:
1Qingcai (青菜) means literally “greenish-blue vegetable” and is used to describe a wide variety of different greenish vegetables, typically mustards (like Brassica rapa). The term is sometimes translated to “Chinese cabbage” or “Bok Choy”, but I went with the direct translation since these English names tend to be rather inaccurate. Besides, most of these qingcai plant varieties do not have good or consistent names in English. Come to think of it, the rather colloquial English term for vegetables: “greens“, may actually be a better translation than the more typical ones.
