Preparation:In bowl, thoroughly mix pork, water chestnuts, ginger
root, green onions, cooked rice, dark soy, sesame oil & water. Allow
mixture to marry for 30 minutes. Form into firm balls, one for each
serving, each the size of a tennis ball (about 3 1/2" across).
Braising:Heat wok or skillet to hot; add oil.When oil begins to
smoke, introduce meatballs 1 at a time, so as not to cool oil. Fry
meatballs until a brown crust has formed. They must be well crusted
in order to retain their shape while stewing.
Cooking in Sandy Pot:Line sandy pot with shredded Chinese mustard
cabbage; sprinkle with pan oil from meatballs, salt & sugar. Add
meatballs, then add cool or cold stock. Bring slowly to boil; cover;
reduce heat to medium & simmer for about 2 hours. Correct seasoning
if necessary. Serve.
