Instead of Ginger tomato sauce

Tomato purée
Use the same weight and stir in ginger paste to taste, about 5% of the purée weight. Simmer briefly; close in body, fresher and less sweet.
Ketchup
Use the same weight and add a pinch of ground ginger. Sweeter and more vinegary; reduce added sugar in the dish.
Canned chopped tomatoes
Use the same weight, blend smooth and cook down with ginger paste until thick. More watery at the start, so allow extra simmering.
