I made this soup with bits and pieces from the fridge. I wasn’t planning on posting any recipe so I didn’t bother taking step-by-step photos.
But the soup turned out so well that I changed my mind about writing a recipe for it. And never mind the lack of step-by-step photos. The cooking process is so simple that a visual illustration is simply unnecessary.
Bok choy stalks are used here. The leaves were saved for another dish. It is up to you whether to use the stalks only or include the leaves. Just note that the stalks will need a longer cooking time. For more about bok choy, see the linked post below.
How to cook Chinese cabbage
When a recipe calls for “Chinese cabbage”, what exactly should you buy and use for the dish? Here’s a practical guide.
What mushroom is recommended? I used fresh brown button mushrooms but just about any variety will work. Shiitake or shimeji should be especially good. If you plan to use dried shiitake, check out the guide for rehydrating.
How to rehydrate dried mushrooms
Yes, you just soak them in water. But what should be the temperature of the water? And how long do they need to soak? How do you know when they are sufficiently rehydrated?
What about the broth? What kind of broth is best? Well, let’s see… if you regularly make broth and you keep containers of the stuff in your freezer then, by all means, use it. Nothing is better than homemade bone broth. If you need a guide, see how I make chicken bone broth.
How to make chicken bone broth
Nothing beats the richness and flavor of homemade chicken bone broth. I make it with soup bones, divide it into portions and freeze until needed.
With all those guides to help you with the very few ingredients in this recipe, let’s look at how fast and easy it is to make the soup.
