Also known as ``Dragon Well tea``, Like most other Chinese green tea, Longjing tea leaves are roasted early in processing (after picking) to stop the natural oxidation process, which is a part of creating black and oolong teas.

Dim sum dishes are usually served with tea and together form a full tea brunch. Due to the Cantonese tradition of enjoying tea with this cuisine

commonly served either as a snack, small meal or as a variety of dim sum. It is a thin crépe roll made from a wide strip of shahe fen (rice noodles), filled with shrimp, beef, vegetables, or other ingredients.

When served during dim sum, the cake is usually cut into square-shaped slices and pan-fried before serving. The cake is soft, but holds its shape after the frying. Sometimes the cake is made with chopped water chestnuts embedded into each square piece with the vegetable being visible.
