Japanese Salad Dressing

I just made this salad dressing in order to use up some fresh lime that was about to be not so fresh, and because I'm tired of my old standby, honey mustard.  It goes something like:

a cm of fresh ginger
the juice of 1/2 a lime
a  tbsp daikon, shredded
1 heaping tbsp miso paste
1 1/2 heaping tsb mayo
tsp soy sauce
dash of rice vinegar

Mix that shit together in a jar.

I blanched the ginger for about 3 minutes, but it was still so spicy and strong that I ended up using maybe as much as a mechanical pencil eraser.  I smashed and ground it.  Perhaps dried ginger freshly ground would be better, but certainly not ginger powder.  I also thought of using pickled ginger but was afraid it would be too cloying.  The daikon doesn't add much flavor but it adds a certain coolness and a nice weight and texture to the mixture.  My salad consisted of romaine, roma tomato, shaved carrots, red onion, red pepper, and an avocado that actually sent me to the emergency room (two stitches where my pinkie meets my palm, and thats why me da always told me to cut away).  Three hours after I started to make the salad (most of it spent in the waiting room), I finally got to try it and it was out of this world! My roommate Malcolm called it, "fucking delicious and I'm not just saying that" if I remember correctly.  If Joey brings any wasabi paste back from Mitsuwa in Chicago, then I would really like to try spicing this recipe up!
