One of the first muffin recipes I collected when we lived at 503 Palomino.

1/3 Cup shortening
½ Cup sugar
1 egg
1 ½ Cups flour
1 ½ teaspoons baking powder
½ teaspoon salt
¼ teaspoon ground nutmeg
½ cup milk
½ cup sugar
1 teaspoon ground cinnamon
½ cup butter, melted

In a mixing bowl, cream shortening, sugar and egg. In separate bowl, combine flour, baking powder, salt, and nutmeg. Add dry mixture to creamed mixture carefully alternating with milk, just until damp. Fill greased muffin tins 2/3 full. Bake at 325 for 20- 25 minutes or until golden. Let cool for 5 minutes. Meanwhile, combine sugar and cinnamon. Roll warm muffins in melted butter and then in cinnamon sugar. Make 8-10 muffins
