Trader Joe's used to sell a pre-made carrot-ginger stir fry mix, and craving that I decided to make a similar sauce. I put it with carrots and swede* but I suspect it would be nice on lots of things where a sweet-tasting sauce can be used.
*Swede is a kind of turnip, as I understand; not much used in the US but popular in the UK.
The way that I made the sauce, I basically boiled the vegetables in it and allowed it to thicken by reduction that way. If I were going to pour it over something or cook it with something that finishes more quickly than root vegetables, I would probably pre-reduce the sauce.
2 1/2 tbs butter
1/2 tsp salt
1 tsp ginger powder
1 tbs white sugar*
2 tbs brown sugar
1/2 cup apple juice*
1/2 cup water
*I used a no-sugar-added juice. If you are using sweetened apple juice you may need to reduce or omit this extra sugar.
Combine all ingredients in a pan over heat and allow to reduce to 1/2 cup of sauce while stirring regularly. Discard bay leaf before serving.
