As this is a straightforward dressing, use high quality white wine vinegar, as there is no where for any flaws to hide.

Here is a “suite” of dressings that all turn on one basic dressing called “amazu”. Amazu is the dressing you get on your basic sunomono, or cucumber salad at Japanese restaurants. The rest are just variations on a theme. When it comes to oil, I keep it very light. Instead of the basic 3:1 ratio of vinaigrette, if I use oil with this dressing I go very lightly, making what is sometimes called a “slack” in restaurants. The idea is to use just enough to help the flavors stick to the food. Usually, this is something like a 1:1 ratio.
