Chinese-Style Baby Bok Choy with Mushroom Sauce Review

I have never seen potato starch so I used corn starch instead. I doubled the sauce but only because I added shrimp to the mix to make it a more hearty meal. We do not have baby bok choy in my neck of the woods so I used regular but I can only imagine how much better this would have been with it. Wonderful recipe and one I will make often. Thank you!
