I always order this when eating Dim Sum. I finally got a good recipe for this off about.com, which re-posted Evelyn Chau's recipe from her book "Have Some Dim Sum". My recipe is modified to suit me. The first time I made this I didn't have orange rinds and so something was off but this time I had an orange on hand and used a cheese grater to grate off some orange skin and wow that's the secret ingredient.
