Put the chopped potato and the 4 cups of water in a saucepan and simmer until the potatoes are tender. Drain, reserving the liquid in a bowl. Mash the potatoes with the butter and salt, add the reserved liquid and set aside.
-
Place the yeast in 1 cup of warm water and let it rest for 10 minutes.
-
In a very large large bowl, stir together 6 cups of bread flour, sugar and the potato/water mixture. When the mixture has cooled to lukewarm, add the yeast. Stir until nice and smooth. Cover and rest for two hours. I mean, let the bread rest for two hours.
-
Mix the spices and remaining flour {5-6 cups, it really just depends on how much you need to make a nice, soft dough}. Add the raisins and then turn the dough out onto a floured work surface and knead until smooth.
-
Place the dough back in the unwashed bowl and cover. Let rise until double.
-
Shape into loaves and place in greased pans {the recipe made four medium loaves for me, six smaller loaves for Shirley}. Let the dough rise again, covered, until doubled in size.
-
Bake at 375 degrees for 30-40 minutes. Cool.
-
While the bread is baking, pull out your mixer and beat the butter, sugar and vanilla together, adding milk as needed {you want the icing to be nice and thick}.
-
Once the bread has cooled, top the loaves with icing and let it set.
