I have been eating these rolls since I was a kid. I don't know where they started out, but I remember my grandmother making them. They freeze well and taste great split open and toasted.
Recipe Summary test
You can substitute 5 tablespoons unsalted butter for the vegetable shortening, if you like.
I roll out the dough to about 1/2 inch thick, cut out 4-inch diameter circles, brush with melted butter-olive oil mixture, and fold over to make half circles. I then brush the tops with the butter-oil mixture when the rolls are done.
