1 cup warm water.
2 pkg yeast
1/2 c butter, melted
1/2 cup sugar
3 cups whole wheat flour
1 1/2 cups all-purpose flour
Combine the warm water and yeast in a large bowl. Let the mixture stand until yeast is foamy, about five minutes. Stir in butter, sugar, eggs and salt. Beat in flour until dough is to stiff to mix (you may not need all the flour) Cover and put in the refrigerator 2 hours or up to four days.
Grease a 13x9" baking pan. Divide dough into 24 equal-size pieces. Roll each piece into a smooth round ball. Place balls in even rows in the prepared pan. Cover and let rise until double about one hour.
Bake in a 375 degree oven until rolls are golden about 15-20 minutes. Bush with melted butter.
