Russian Salad Dressing

This is my Grandma Carlson's recipe. It is from the first cookbook she ever owned--the Lighthouse Cookbook. She was born in 1915 so I am very curious about that old cookbook and wonder if any of my aunts or uncles have it.  

This is probably the first salad dressing I ever made, but I haven't made it in years. Kellie decided to resurrect the recipe for Sunday dinner last week. It was a nice change.

Russian Salad Dressing

1 small onion

1/2 cup white vinegar

1 or 2 small cloves garlic

2 tsp. Worcestershire sauce

1 tsp. paprika

3/4 cup sugar

1 can condensed tomato soup

3 tsp. dry mustard

2 tsp. salt

3/4 cup salad oil

Put all ingredients in blender except oil. Cover and run at low speed, about 2 seconds. Turn on high and mix until well blended. While still blending slowly add oil.
