SAUCE MIX:

1 tbsp. instant nonfat dry milk
1 tbsp. flour
1 tbsp. cornstarch
1 tsp. salt
1/2 tsp. onion powder
Dash of pepper

Combine the above ingredients to make 1 package of sauce mix. For extra convenience multiply the sauce mix ingredients by 4 or 8 and store in a jar with a tight fitting lid at room temperature. Use 3 tablespoons sauce mix to equal 1 package.

TO USE:

3 c. potatoes, sliced 1/2 inch thick
1 c. hot water
1/3 c. milk
1 pkg. (3 tbsp.) sauce mix
1 tbsp. butter
1/2 c. cheddar cheese

Place potatoes in pot and cover with the cup of hot water and quickly bring to a boil; cover the pot, lower the heat and gently boil for 5 minutes or until the potatoes are just tender. Pour the cooking water from the potatoes into an ungreased casserole dish; pour the milk into the casserole; then blend in the package of sauce mix. Add the potatoes and dot with butter and sprinkle with cheese. Bake at 350 degrees for 30 minutes.
