2 teaspoons sugar
1 ½ tablespoons hot water
3 tablespoons apricot preserves
1 salted pickled plum
½ teaspoon liquid from salted pickled plum jar
1/8 teaspoon soy sauce
1/4 teaspoon rice vinegar
In a small bowl, mix the sugar and hot water until the sugar is dissolved. Add the apricot preserves.
Remove pit from the pickled plum and add to the bowl. The plum is very soft and should fall apart. Then add ½ teaspoon liquid from the pickled plum jar, soy sauce and rice vinegar.
Mix everything together with a fork until the duck sauce is well-combined. Let the sauce sit for 5 minutes and mix again.
