1 1/2 teaspoon finely chopped ginger root
1/4 cup chopped onion
1/4 cup chopped carrot
2 tablespoon chopped celery
1/2 cup soy sauce
1 cup peanut oil
1/2 cup vinegar
Blend together onion, carrot and celery until very fine. Add other ingredients, including freshly ground black pepper if desired. Shake well before use.
Best made a day ahead for flavors to meld.
