This tastes just like the Gai-Lan that my DBF and I get when we go to Dim Sum on Sundays. It is really easy to make at home. It is similar to regular broccoli but it is slightly milder and has broad flat leaves instead of florets. If you can't find Gai Lan, you can substitute broccolini. The baking soda helps the broccoli retain its green color while cooking.
