White Gravy

¼ cup shortening (sausage grease is best)
¼ cup flour
1 pint milk
½ teaspoon salt (if grease is not salty)

Heat grease until fairly hot. Slowly add flour, stirring until smooth.
Gradually add milk, stirring until gravy thickens.
If necessary for proper consistency, stir in a little more flour.
Stir in salt if needed for flavor.
