Long leaf vegetables are a key component of most meals at our house, and yuchoy is a vegetable that comes fresh to Philadelphia markets regularly. That is to say it is usually in our fridge. It keeps pretty well for 3-5 days, so we can eat a bag over two or three meals, alternating with other vegetables.
Yuchoy 油菜 (or youcai in Mandarin) literally means “oil vegetable”. This is because it is closely related to the plant that produces rapeseed oil (aka canola oil). The vegetable is delicious chopped into bite size segments and stir fried with oil, garlic, and soy sauce. It is also nice in savory soups (like the Northern Thai stew “boiled greens” which I wrote on a few years ago.
I ate this vegetable often while living in Guangzhou in the 90s–it is very common there, so it is perhaps fitting that is frequently referred to by its Cantonese name in Philadelphia. The version of this vegetable commonly found in markets across Thailand–with longer stems and bright yellow flowers–is called simply gwangdoong vegetable, or ผักกวางตุ้ง (i.e. Guangdong Province). That variation might be referred to here by the Cantonese name “heart” of yuchoy, or yuchoy sum 油菜心.
My favorite way to prepare this vegetable is to simply blanch it for a minute or so and top it off with a quick mixture of oil, soy sauce, oyster sauce, sugar, and water heated in a pan. From start to finish, this dish can be done in five minutes or less. Needless to say, we eat this a few times a week because it is so fast and easy.
One tool I would recommend is a wide shallow pot. My pot of choice is one that is meant for Korean hotpot–it is made from lightweight material that helps water quickly come to boil. I find myself using this pot several times each week, whether to blanch whole vegetables, or to boil long dried noodles. Its width makes it possible to quickly blanch or boil things things that are long or awkwardly shaped.
Recipe: Blanched yuchoy 清煮油菜
This recipe is so easy I’m almost embarrassed to post it here. Still, I realize that this simple preparation maybe hasn’t occurred to some readers–hopefully those people will be inspired to try it:
1. Bring water to boil in your pot, pan, or wok. Toss in a spoon of salt.
2. Wash vegetables. Give them a good rinse. If the sliced part of the stem is discolored or wilted, feel free to trim it a little bit. Don’t worry about draining them well–they’re about to go back into water. If you didn’t do a good job cleaning them, it likely won’t make much difference–the boil is like a second cleaning! I used a good handful of yuchoy, enough for 2 people as an accompaniment.
3. Put vegetables into the boiling water and use chopsticks or another utensil to ensure they get submerged. Boil covered or uncovered for 1-2 minutes. Stems will start looking bright green.
4. Turn off the heat. Take the yuchoy out of the water. I like to take them out one by one and stack them on a plate. Notice how I do that, with the plate tilted to drain water off back to the pot.
5. This is also optional, but I like to chop the vegetable on the plate into bite-size segments.
6. This part is also optional and highly customizable… you can serve the vegetable as is, or with some sort of a seasoned topping. I like a combination of oil, oyster sauce, soy sauce, chopped garlic, and sugar (with a little water to keep it from burning). You can premix those things or just add them one by one to the pan. I used one clove of garlic, and 1/2 tsp sugar, and about 1 tsp each oil, oyster sauce, soy sauce, and water.
7. Drizzle optional topping over vegetable
8. Enjoy with rice and some other accompaniment. Today this is breakfast, and I enjoyed the yuchoy with a rice and a fried egg:
Thank you so much for posting a picture of the raw vegetable. I see so many goodies at the mkt but have no idea what they are. Trying to pronounce them for store help is hopeless. Our daughter, who speaks some Mandarin, says “Dont bother, Mom.” So any pics of unfamiliar ingredients is very helpful. (Thanks to you, I use ya cai pretty often now.)
That’s very kind of you to say David. Happy to help in this regard!
