1 clove garlic, minced
3 c. onion, thinly sliced
5 tbsp. butter
3 tbsp. flour
2 c. water or vegetable broth

3/4 tsp. dry mustard
1/2 tsp. horseradish
1 1/2 tsp. salt (or to taste)
Black pepper

Melt 2 tablespoons butter in a Dutch oven or large saucepan. Saute garlic, onions, mustard and salt until tender. Cover with water or broth and simmer.

In another saucepan, melt remaining 3 tablespoons butter. Mix in flour, stirring constantly, for 1 minute. Add warmed milk slowly to flour mixture, beating constantly. Cook until thick and smooth, 5-6 minutes. Add horseradish and cheese. (May add 1-2 tablespoons dry sherry if desired.)
