Creamy Ginger Dressing

This is stolen from Caitlyn Dahl's blog...I decided I would post if for her. She said it's the dressing from Bennihana's and Tepanyaki.

"If you have tried it, you know how good it is" said Caitlyn It is a creamy ginger dressing. Here is the recipe:

1/2 c minced onion

1/2 c sesame seed oil

1/3 c rice vinegar

2 T water

2 T minced fresh ginger

2 T minced fresh celery

2 T Ketchup

4 t Soy Sauce

2 t sugar

2 t lemon juice

1/2 t minced garlic

1/2 t salt

1/2 t ground black pepper

Combine all ingredients in a blender. Blend on high speed for about 30 seconds or until all ginger is pureed. Chill. Makes 1 3/4 cups. (I doubled this recipe)
