I was looking through Grandma June's recipes. I came across this one dated 1952 from the kitchen of Ingrid Olsen. It's in June's handwriting. The directions in parenthese are also included in the recipe. Poppy Seed Dressing Makes (3 1/2 cups) 1 1/2 cup sugar 2 tsp dry mustard 2 tsp salt 3/4 cup white vinegar 3 tsp onion juice 2 cup Wesson oil (never olive oil) 3 tsp poppy seeds Put in electric blender sugar, salt, mustard,vinegar. Add onion juice and mix thoroughly (get onion juice by putting onion in blender and straining) Add oil slowly, beating constantly and continue beating until thick. Add poppy seed and beat for a few minutes. Store in refrigerator. Will keep indefinitely! Have oil at room temperature.
