Here's my version of
Old Milwaukee Rye:
2 3/4 cup water
2 1/2 tsp yeast, instant
3 tb oil
2 tb caraway seeds
1/4 cup(s) blackstrap molasses
1 large egg
1 tb salt
4 cup dark rye flour
3 - 3 1/2 cups Whole Wheat flour, plus 1 c bread flour, OR
4 1/2 c Bread flour
A. Up to three days before bake day, combine 1 1/2 c water, 1 tsp yeast, 2 c rye flour, and 1 tb caraway; mix well, cover, and let rise at room temp. to sour.
B. On bake day: stir in the remaining yeast, rye flour, caraway, and water, along with the molasses, egg, oil, and salt. Stir in 3 c WW flour Or bread flour, if using all bread flour), and set aside 15 min. Mix in the 1 c of bread flour, saving last 1/2 c of WW flour if needed. Knead 6-7 min with dough hook. Place dough in a large oiled bowl, and roll around to coat. Let rise 1 1/2-2 hrs., or until doubled. Punch down and let rest while greasing three 8 1/2"x4 1/2" pans, or two 9"x5" pans, or two 10" x 4 1/2" pans. Divide evenly and place in pans, cover, and let rise until doubled, about 45 min. May be made into free-standing loaves, as well. Slash 3-4 times with these. 15 min before rise is finished, preheat oven to 375º, 325º in a convection oven.
C. Bake 45-50 min., 40-45 min. in the convection oven. Cool on a wire rack.
The original recipe had only 3 c rye, and 5 1/2 c AP flour, as this book came out when bread flour was not available most places! Now bread flour is available, and I even add a little when I also use WW flour, and this needs some extra gluten, since I increased the rye.
I often use this method of making a sour mash with other rye breads, when I don't want to bother with a sourdough.
