Cream butter and sugar until fluffy. Add rum and blend well. Gradually add flour
to butter mixture. Blend in enough flour to make a smooth ball. Chill 1 hour.
Take pieces of dough and roll into balls the size of a walnut. Drop into melted
butter, then nuts, and into cinnamon-sugar. Shake off excess and place on cookie
sheets. Bake 15-20 minutes or until golden brown.
