咕老肉 Sweet Sour Pork
A classic dish from North East (Dongbei) China, originating in the city of Harbin, Heilongjiang Province. It consists of large thinly sliced pieces of pork in potato starch batter, deep-fried twice until crispy. They are then lightly coated in a variation of a sweet and sour sauce, made from freshly prepared syrup and rice vinegar, flavored with ginger and garlic. The batter absorbs the sauce and softens. A Beijing variant has the sauce thin and watery, while the dish as prepared in the North East is often a thicker sauce with some ketchup added to it. However true 咕老肉 Sweet Sour Pork is made with an amber colored sauce due to the fact that it uses caramelized sugar.
