When Owen and I lived together, he would often make dumplings. Often means about 25% of the meals and would account for 55% of his caloric intake. Making the dumplings themselves was reasonably easy (ok, we were using the frozen kind) but the creation of his dipping sauce was a sight to behold, as he scurried around dispensing careful drops from exotic bottles.
Lucky for me, he has given me a cheat sheet so that I can reproduce this sauce in Boulder. Here it is for your dipping pleasure:
Warning: Owen had to stop eating spicy food for several months after eating this delicious sauce.
