Sift whole wheat flour, all purpose flour and salt. Set flour mixture aside.
Mix dry yeast, 1/2 tsp. sugar and 1/2 cup lukewarm milk. Let yeast mixture sit for 5 minutes.
Mix flour mixture and yeast mixture together. Add melted butter and mix until dough forms.
Place dough in greased bowl, cover with plastic wrap and set aside in warm place for about 1-2 hours or until doubled in bulk. Punch dough down and allow to rise about 20 more minutes.
Knead dough on floured surface. Flatten dough to about 1 inch thick and cut with biscuit cutter. Place muffins on griddle and cook for about 7 minutes per side. Remove to cooling rack. Serve warm with butter and jam of your choice. Yum!
