I served this as a starter dish one evening.
This is not really a recipe. I just washed and cut the garlic chives into one inch long pieces and blanched them for a few minutes then let them cool down before using. The dressing is a mixture of Japanese mustard (from a tube), sugar and soy sauce.
Although in the past few garlic chive dishes, I complained that there was not enough garlic chive flavor in this one there was perhaps a bit too much. The garlic chive was also a bit chewy as well and my wife gave up on eating it. Since I made the dish I persevered and finished it. This dish requires some improvement.
