3/4 c. salad oil
1/3 c. sugar
3 tbsp. red wine tarragon vinegar
1 1/3 tsp. onion juice
3/4 tsp. salt
1/4 tsp. dry mustard

Combine all ingredients in food processor. Blend until well mixed. This is a very pungent dressing, but good on spinach salad. (Note: Don't expect anyone to kiss you after eating this dressing!)
