This makes enough for several large salads.
3/4 cup sugar
1 teaspoon dry mustard
1 teaspoon salt
1/3 cup vinegar
1/2 medium onion -- pureed
1 cup salad oil
1 tablespoon poppy seeds
Place onion in blender and puree. Add mustard, salt and vinegar. Mix in sugar. While blender is going, slowly add oil. Continue to blend 2 minutes. Add poppy seeds last.
Delicious with any salad that mixes spring greens, sharp, pungent cheese, fruit, and nuts.
