What is choy sum?

This beautifully leafy green is available at all Chinese supermarkets year-round, and if you have a local Asian community, you might find it at your local farmer's market too. Sometimes, it's alternatively labeled 油菜 "yu choy".

The flavor is sweet and delicate, and the texture is similar to bok choy, lighter than other heartier vegetables.

Its appearance is a bit similar to gai lan. How do you differentiate between them? Choy sum is a lighter, brighter green compared to gai lan's dark, almost blue-green leaves.

The stems are quite different as well; choy sum stems are curved and rather flexible, while gai lan stems are round and dense, like broccoli.

No blanching?

Stir-fries that involve heartier vegetables often call for blanching as a pre-cooking stage. Blanching a hearty vegetable ensures that it's tender enough for a pleasant eating experience.

Choy sum, however, is tender enough to stir-fry straight from raw (after washing and trimming, of course). In Cantonese cooking, this is called 生炒 (saang1 caau2). No pre-cooking necessary!

To prepare the choy sum (1 lb), you want to separate the quick-to-cook leaves and the slower-to-cook stems.

You can either make one horizontal chop to separate the leaves and stems of each plant all at once, or you can cut apart the stems (at an angle for extra style points) and then chop away the leaves to separate.

Slice the garlic. For maximum visual appeal, leave some of them sliced (2 cloves) and mince the rest (3 cloves).

Cut the ginger ( small amount) into roughly 1/8 slices. In our video, we used about 4 slices of ginger for 1 lb of choy sum.

Heat your wok over high heat for a quick minute. Add a dash of oil (1 tbsp), then turn the heat to medium low. Lowering the heat here is important to avoid burning the aromatics.

Add the ginger and garlic. Stir-fry for 15 seconds so that you can smell the ginger and garlic releasing their aromas.

Add the stems first, since they'll take longer to cook through. Stir-fry the stems for about 30 seconds.

Then, add the leaves.

Raise the heat to high and add cooking wine (1 tsp) and sugar (1 tsp) to balance the texture of the leaves; these ingredients help make the dish silky smooth. Mix the seasonings in and stir-fry for another 30 seconds.

DON'T ADD THE SALT YET! If you add salt now, all the water in the vegetables will release (thank you, osmosis) and you'll end up with less tender vegetables in a puddle of juice.

Lower the heat to medium or low heat. Cover with the lid and let it steam for about 1.5-2 minutes, or until the choy sum is tender and just cooked through.

Uncover the wok and bring the heat up to the highest setting. Stir-fry on high heat for a minute, then add salt (0.50 tsp).

Drizzle finishing oil (1 tbsp) over the top for a smooth texture, a glossy look, and to help preserve that vibrant green color.

Toss the finishing oil in for another 20 seconds, and then plate. Enjoy!

FAQ

How do you pick choy sum?

  • Younger plants are tender and more sweet, so go for the smaller, brighter-looking choy sum that have slimmer stems. Thicker stems have had more time to grow. If the stems are so thick that they have a white core, then they're definitely mature and probably not as tasty.
  • Keep in mind the texture. Young choy sum is very springy and elastic. Older plants are stiff and not too bendy; avoid those.

What's the difference between choy sum and yu choy?

  • If your local store or market stall only has one or the other, they're probably using that name for the same thing. If you get to choose between the two in the same store, then there is a very slight difference between them.
  • Yu choy is a more overarching name for the plant. It can range from bigger, more mature plants, which are tougher in texture, to smaller, younger plants. If you see yu choy next to choy sum at the store, then yu choy will typically be the bigger, tougher plants.
  • Choy sum is the tender inner part of the young yu choy plant. Technically, choy sum is called "yu choy sum", so you might even see that name floating around.

How do you prepare choy sum for cooking?

  • Always wash your greens! If there are woody ends or the stem is thick enough to have a white core, trim those off. They'll be tough and difficult to eat.
  • The leaves are quick to cook and the stems take longer, so you usually want to separate them to better control the texture of your dish.
  • You can either make one horizontal chop to separate the leaves and stems of each plant all at once, or you can cut apart the stems and then chop away the leaves to separate.

Do you have to blanch choy sum?

  • No, choy sum is tender enough to stir-fry straight from raw. In Cantonese cooking, this is called 生炒 saang caau. No pre-cooking necessary!

How do you prevent stir-fried choy sum from going soggy?

  • Our recipe directs you to cover the wok with a lid for 1.5-2 minutes. If you prefer your choy sum with more of a bite, tend more towards the 1.5 minute range, or even shorter. You can shorten the aromatic-frying step too.
  • Make doubly sure that you're not adding salt until the end. Extra water in the wok will definitely contribute to sogginess!
