Guangdong Cuisine states a vital position in southern China, and Guangdong people inherit the natural fond of leafy vegetables by generations. The most common cooking method for Yu Choy in Guangdong Cuisine is the “boiled method,” where the Yu Choy is boiled firstly and followed by seasoning with soy sauce, oyster sauce, and minced garlic, thus preserving the original taste and nutritional value of Yu Choy to the maximum extent. The boiled method, which is assumed by many people a simple cooking process of scalding, is a technique from the Guangdong Cuisine that requires solid skills, where time and manner of scalding may vary according to different ingredients.

The first experience of the Boiled Yu Choy by a restaurant chef happened when I wasn’t armed with such knowledge, so I thought it’s a simple dish. However, I changed my mind when I got the fresh Yu Choy home and prepared to show my stuff. I found that this seemingly simple boiled Yu Choy was not as easy as I thought. I worked on the dish several times, then only slowly summing up some experience, yet it was still far from the level of a restaurant chef.

What ate the matters needing attention while cooking the Yu Choy?

  1. Nothing is more important than freshness for leafy vegetables. A delicate dish starts with ingredients purchasing. You don’t want to choose the Yu Choy with too much wilting, or with a dried-up stem, which are signs of losing freshness; you want fresh ones.
  1. As for the washing process of the vegetable. It is recommended to follow a 15 minutes soak for leafy greens. I would love to advise you guys not skip this step, as it helps to remove the residual dirt on the vegetables effectively.
  1. The stem of the Yu Choy is thicker and stronger than the leaves, which requires more prolonged cooking on the stem before it’s cooked. Therefore, in the boiling process, the stem shall be dealt with firstly, then only followed by the whole Yu Choy boiling in the water. In this way, we can prevent the leaves from over-boiled. Vegetables lose their nutrition when they’re over-cooked, no matter for Yu Choy, or other types. It is essential to master the time of Yu Choy being boiled. My personal experience indicates to complete the boiling process within 2 minutes. Generally speaking, when the color turns to dark green, it’s about the time.

I believe the memory will drive me to the kitchen to trace the delicacy, and I think there will be another recipe of Yu Choy to share if I succeed.
