Cheese Sauce with White Wine

5 tablespoons butter
1 teaspoon dry mustard
5 tablespoons all-purpose flour
4 cups whole milk
1/4 teaspoon salt
1/4 teaspoon ground nutmeg
1/4 teaspoon black pepper
Few drops Tabasco hot pepper sauce
3 1/2 cups grated sharp cheddar cheese
1/2 cup dry white wine

In a medium-size saucepan, melt butter; remove from heat. Add dry mustard and flour and whisk to blend until smooth. Add salt, ground nutmeg, black pepper and Tabasco sauce, mix to blend. Add 1 cup of milk and mix to blend; return to heat. Slowly add the remaining milk, stirring constantly so that the flour mixture does not settle and start to go lumpy. Just before the milk starts to boil, add grated cheese in small amounts, stirring constantly. Reduce heat and continue cooking for about 3 minutes longer until mixture comes to just boil and is well blended. Stir in wine and cook for 1 minute longer. Makes about 8 to 10 servings.
