In a small sause pan place the first 4 indredents (soy, sugar, garlic, ginger). On medium low-heat simmer this mixture till it reduces by at least half the amout, if not more. Consistancy for me has to be like molasses. I love the flavor of this and like it to stick to what im eating. Remember, you will be cooling this so it will get even thicker as it cools. You dont want it to think to use. Cool to room temp.
