Ingredients
Directions
Scald the milk in a pot until it boils, then remove from heat.
Add the lard to the milk and let it cool.
Once cool, stir in the sugar, salt, and yeast until combined.
Let the mixture rise until well risen, about noon.
Cut down the risen dough with a knife and let it rise again until light.
Roll out the dough to ½ inch thick and spread with butter.
Cut the dough with a biscuit cutter and fold each piece over.
Place the rolls in tins close together.
