Like it’s close cousin cabbage, this green can be prepared in many ways. The main thing to remember is that it needs to be cleaned properly. Unlike a head of cabbage, the Baby Bok Choy has an open leaf structure that can hold dirt.  This means you need to do more than wash the outside. First, remove any damaged leaves. Then, cut the bok choy bundles in half lengthwise.  Next, soak in a bowl of cold water. This will clean the leaves and any dirt stuck in between the leaves will come away and sink to the bottom of the bowl. Finally, remove from the water and let dry on a paper towel or clean dish towel.
