This recipe tasted good. I did not have any sesame oil, so I left it out. I thought it was a little too tagny, so I added about another teaspoon of sugar. I will make this again.
This is a good recipe to experiment with.

Try adding less than half of the rice vinegar, then taste. I warmed on the stove with chopped scallion and additional sugar, then used water to double the total amount of liquid. Then it was similar to dipping sauce in Asian restaurants.
