You can use soy sauce to taste.
The amount of ground Ginger added to this recipe over powers the dish. I suggest that you halve or even only add 2 Teaspoons of ground Ginger and not 2 Tablespoon as the recipe asks. Also add 2 Tablespoons of water rather than 2 teaspoons. I will give this recipe another try with adjustments to the ginger & water. - 02 Jan 2014
Not the best recipe, it needs a lot of amendments to taste good, but I like the general idea of pork with plum sauce. - 01 Sep 2017
