One minor correction:
dim sum (点心) are what you eat, but the experience of eating them in company with large quantities of tea is
yum cha (飲茶 in
traditional style).
There used to be a Dim Sum metanode linking up all of DMan's scrumptious recipes (and probably a few others), but as far as I can see it has disappeared off of the face of Everything. An attempt at a recreation -- compiled
by hand by wading through 800+ writeups, mind you --
can now be found within the Cookery catalogue
at Cookery : Recipes, regional : China : Cantonese.
