Spinach Salad Dressing

This is the recipe that went on the spinach salad.

3 cups Sugar
2 Tbsp Dijon Mustard
3 Tbsp Chopped Red Onion
1 1/2 Tbsp Poppy Seeds
4 tsp salt
2 cups Vinegar (we use apple cider vinegar)
2 cups Oil
You may have to make in half portions if your blender is not large.

Blend all ingredients in the blender except for the oil. The oil must be added after all ingredients and while the blender is running. If you add it without the blender running it will seperate and you will have to shake it well before each time you use it.
