In a small bowl, dissolve yeast in warm water. Set aside.
In a saucepan, over low heat, melt butter and add sugar, salt, milk and oil. Gently warm until tepid. Pour butter mixture into a large bowl and add eggs, mixing thoroughly. Add 1 cup flour and mix. Add dissolved yeast mixture and combine well.
Add remaining flour 1 cup at a time to form soft dough. Dough should pull away from sides of bowl and not he sticky. Cover and let rise in a warm draft-free place until doubled in size.
Punch down dough and divide into 24 balls, each a little larger than a golf ball. Roll each ball into a rope about 8 inches long. Tie into a knot and place on greased cookie sheet. Let rise until doubled in size. Preheat oven to 325 degrees. Prepare egg wash and brush each roll completely.
Bake in preheated oven until golden approximately 25 to 30 minutes. Makes 2 dozen rolls. Enjoy!
