Yu choy (also edible rape) is a green leafy vegetable used in Chinese and Southeast Asian cooking.[1] Younger and/or more tender varieties are often called choy sum.[2][1]



Yu choy consists of branching stalks with a couple broad leaves at the end of each and, sometimes, yellow flower heads. The texture when raw is somewhat crunchy, though it gets tougher as it ages.[1][2] Most varieties are green, though purple/red cultivars exist as well.[1] The flavor is grassy with a slight bitterness that, again, increases with age.[1][3]

The vegetable looks very similar to gai lan, but it is more tender and has a slightly different flavor.[4]



Technically, yu choy is a cooler weather vegetable, but it does tend to be available year-round.[1]

Selection and storage


Like other leafy greens, look for bright green yu choy that has no wilting, browning, blemishes, or sliminess.[1] The younger and smaller, the more tender the stems.[1] Additionally, those with more flowers may be more bitter.[1] It can be stored, unwashed, for a few days in a container in the fridge. If you want to freeze yu choy, it's best to blanch it before doing so.[1]

Yu choy is popular in Cantonese cuisine, where is is often steamed or stir-fried with strong flavors.[3][4][5] Tougher stalks can be separated from the leaves and braised for longer in order to tenderize them, but don't overcook them.[1] To prepare yu choy, trim any tough parts off the stem. Particularly thick or fibrous stems can be peeled.[3]



If you can't get your hands on yu choy, gai lan or tender bok choy will make for reasonable approximations. Rapini is also an option, though it is more bitter.[1]
