1 1/2 c. sugar
2 tsp. dry mustard
2 tsp. salt
2-3 c. vinegar
3 tbsp. onion juice
2 c. salad oil (but never olive oil)
3 tbsp. poppy seed

Mix together sugar, dry mustard, salt and vinegar. Add onion juice and stir thoroughly. Add oil slowly, blending constantly until thick. Add poppy seed and beat for a few minutes. Store in cool place or refrigerate. Never freeze.

If dressing separates, pour off liquid and start all over blending with the poppy seed mixture (too warm or too cold will cause it to separate).
