Poppy Seed Dressing

2 tsp. dry mustard 

2 tsp. salt 

2/3 c. white vinegar 

3 T. finely grated onion 

2 c. salad oil (never olive oil) 

3 T. poppy seeds 

Mix sugar, mustard, salt, and vinegar in a blender or food processor. Blend in onion. Add oil slowly beating constantly, and continue beating until thick. Blend in poppy seed. Serve over grapefruit and avocado sections or any fruit salad. Helen Corbitt warned that cold or heat will make the mixture separate. Don't despair, just pour off the oil on top and repeat the blending process.
