Preheat oven to 425F.
In a mixing bowl, sift together the flours, baking powder & salt. Work in the margarine till the mixture resembles coarse breadcrumbs. Add apple juice, potato, honey & nuts & work till it resembles a soft dough.
Turn dough out onto a well-floured board & knead enough extra flour to make the dough lose its stickiness. With floured hands, divide dough into 16 equal parts. Shape into small balls & arrange on a lightly oiled cookie sheet, patting them down a bit to flatten them. Bake for 12 to 15 minutes.
Serve hot with Creamy Mushroom Soup.
