Step 1

In a small bowl, add all the ingredients from jam to sugar, if using. Mix well until there are no clumps. Adjust the seasoning to taste. The sauce should taste sweet, sour, and a little salty at the same time with pickled plum flavor.

Step 2

Japanese or Chinese pickled plum tastes salty, sour, and with a hint of sweet flavor. To use it, remove the seed and use a fork to mash it into a paste. You can also use a small fine strainer and a spoon to press the plum through the sieve to make a fine paste.
