Plum Sauce Recipes

2 heaping spoonfuls plum jam (about 1/4 cup, I think)
1-2 Tbsp soy sauce
1/2 tsp hot chili oil
1 tsp sesame oil
1/4 tsp freshly grated ginger
(1 tsp rice vinegar or sherry)

The plum jam I used was very sweet (compared to the stuff I used to get), so
I added more soy sauce and some rice vinegar to cut the sugar. The soy and
chili oil are the most important additions.
If the result is too thin, mix (maybe a teaspoon) cornstarch with enough
water to make a paste, add that, and then cook the mixture till it bubbles
a little. It should thicken upon cooling. (The plum jam will thin out when
heated, so it ends up thinner when warm than before you added the cornstarch.
Fear not.) You can make it all ahead of time and store in the refridgerator,
so there's time to make adjustments.
I was wrong about needing the microwave - now that I think about it, I used
a pot on the stove when needed. I didn't need it for the stuff I made last
night, but if you're using it on moo shoo or something, make sure it's thick
so it doesn't leak out.
