1. In a large bowl add white flour, cocoa, yeast, caraway seeds, gluten and salt in a large bowl. Stir to mix.
2.Place water, honey, and oil in a glass bowl or measuring cup and heat in microwave for 1-2 min. until liquid mixture is about 110 -115 degrees, add to dry ingredients and mix until moistened, then beat very hard for 3 minutes.I use my Kitchenaid stand mixer with the whip attachment, then switch to the dough hook to continue with the next step.
3.Stir in rye flour, enough to make a soft dough. Knead 8 to 10 minutes.
Divide dough in half and shape to fit 2 greased loaf pans,Brush tops lightly with oil and cover with a damp cloth. Raise in unheated oven over a pan of hot water for 1 hour until doubled. Punch down and allow to rise again until almost doubled.Preheat oven to 400 degrees F. Bake 25 minutes. Remove from oven and immediately remove from pans; let cool on rack.
