Every day at the Dalles House in St Croix Falls they serve Yorkshire Pudding with a different flavored butter. Ours was Applesauce blended with softened butter and a hint of powdered sugar added to make it spreadable. Another flavored butter is made by combining raspberries and lemon with the butter.
Tastes & Treasures recipe for Refrigerator Rolls would be a nice comparison to these and very easy to make.

1/4 cup lukewarm water
2 cups milk
1 cup (2 sticks) butter
4 eggs
3/4 cup sugar
2 teaspoons salt

Beat the eggs in a mixing bowl until blended. Beat in the sugar and salt. Add the milk mixture and beat until combined. Add the yeast mixture and flour and beat until a dough forms.
Turn the dough onto a lightly floured surface and knead several times. do not allow the dough to become too stiff. Place the dough in a greased bowl, turning to coat the surface. Chill, covered for 2 to 10 hours. Shape the dough as desired and arrange on a baking sheet. Let rise until doubled in bulk. Preheat the oven to 350 degrees and bake for 15 to 20 minutes or until light brown. Decrease the sugar to 2/3 cup for a less sweet dough.
