Benihana-Style Ginger Salad Dressing

Growing up we had a New Year's tradition of eating Japanese food at Benihana in downtown Seattle. Sadly it is lo longer in business in Seattle. However, the memory lives on because I found this copycat recipe of their salad dressing which is delicious and I used to make this for my mom. She loved it! I double the ginger and it is perfect to me, but if you like less gingery spice you can reduce this.
