1 med.-lg. head cabbage
1 lg. onion (I prefer red because it's not as strong)
3/4 c. sugar
1 1/2 tsp. salt
1 tsp. dry mustard
1 c. vinegar
1 tsp. celery seed
3/4 c. salad oil

Coarsely chop 1 head of cabbage. In a large bowl alternate a layer of cabbage with a layer of onion sliced and separated (cabbage, onion, cabbage, onion). Pour 3/4 cup of sugar over all.

In a pan bring to a boil the vinegar, salt, celery and dry mustard. Add 3/4 cup salad oil to the hot mixture after removing from heat and stir. Pour mixture over cabbage and onions. Cover. Refrigerate and stir often. Best if prepared a day ahead.
