Blackbread - Surbrød

Makes 5 small or 3 standard loaves

Mix the yeast, 1 tablespoon water and sugar in a large bowl. Add the rest of the ingredients in the order given. Beat well.

Put the dough on a floured board and knead well. Let rise on the board in a warm place until doubled in bulk. Knead well again and shape into loaves. (5 small loaves are better the 3 standard-sized ones if you have pans smaller than 9 × 5 × 3.)

Put into greased pans and return to warm place to rise until again doubled in size.

Bake 10 minutes in a preheated 425° oven, then lower the heat to 325° and bake 1 hour more. Slice very thin.
