While there's nothing like the traditional applesauce and sour cream, here's a bit of variation. It's easy to make and tastes great.
1/2 cup honey, or to taste
9 medium apples
8 oz bag of fresh cranberries
1 teaspoon lemon rind
Core and cut apples. Cover well with water and cook until soft. Stir occasionally to prevent sticking. Cover cranberries with water and cook until very soft (about twenty minutes). Drain. Put apples through foley food mill (I see them often in second hand stores) or force through colander to remove skins and seeds. Add cranberries, honey, and lemon rind.
Note: Depending how tart or sweet you like your sauce, you can add more honey.
