Sourdough starter, warm water, whole wheat flour, sugar; mix together and let sit and ferment. In another measuring cup, put some yeast, sugar, flour, warm water; when bubbly add to other mixture. Add milk, melted butter, salt.. Add flour until able to turn out and knead. I used a combination of AP flour, Hungarian high altitude flour, and Wheat Montana Prairie Gold. Let rise until doubled, form into rolls, bake.
