5 cups (635 grams) white whole-wheat or regular whole-wheat flour
Approximately 1 1/4 cups (160 grams) mixed whole grains (rye flour, cornmeal, rolled oats or oat flour, amaranth, ground flaxseeds - not more than 30 grams, or cooked polenta, brown rice, or barley, or 7-grain cereal mix)
2 teaspoons table salt or 1 tablespoon kosher salt
1 1/4 cups lukewarm water
1 1/4 cups lukewarm milk
2 1/2 tablespoons honey, or 4 tablespoons brown or granulated sugar
1 1/2 tablespoons instant yeast
1/4 cup vegetable oil
1 large egg
Filling:
1/2 cup granulated sugar
1 tablespoon cinnamon
1/2 cup raisins or currants
2 teaspoons all-purpose flour
1 large egg beaten with 1 tablespoon water
Make the dough:
In the bowl of an electric mixer, whisk together flour, grains, and salt. In a separate bowl, mix together water, milk, and honey or sugar, then whisk in yeast until dissolved. Add egg and oil and whisk until combined. Add to the flour mixture in the mixer bowl. Combine with paddle attachment at the lowest speed for 1 minute. (Or, mix by hand; use a large spoon and stir for 1 minute.) The dough will be wet and coarse. Let rest for 5 minutes.
Switch to the dough hook and mix the dough on medium-low for 2 more minutes. (If mixing by hand, stir for 2 minutes with the spoon). The dough will seem firmer and more smooth; ideally, it should be supple and sticky, but a bit more flour can be added a spoonful at a time if it is still very wet. If it seems excessively stiff, add a little more water, a spoonful at a time. Continue to stir with dough hook or by hand for 4 minutes.
Scrape dough out onto a lightly floured counter. Knead a few times, then form the dough into a ball and let it rest, covered, for 10 minutes. Repeat this process - kneading a few times, then resting for 10 minutes - two more times.
Allow dough to rise for 60 to 70 minutes, until doubled in bulk.
Make the filling:
Combine the sugar, cinnamon, raisins or currants, and flour in a food processor or blender, processing until the fruit is chopped.
Fill the bread and form loaves:
Turn the dough out onto the floured counter and divide it into two equal pieces. Roll each into a long, thin rectangle, about 16x8 inches. Brush the dough with with beaten egg and water mixture. Sprinkle half the filling evenly over the egg. Beginning with a short edge, roll the dough into a log. Gently press the side seam and ends closed, and place the log in a lightly greased loaf pan. Repeat with the remaining dough and filling.
Cover the pan with lightly greased plastic wrap, and allow the bread to rise for about 1 hour at room temperature, or until it has crowned about 1 inch over the rim of the pan, about 45 to 60 minutes. About halfway through the rising time, heat the oven to 350°F.
Bake the bread for about 40 minutes, rotating the loaf once for even color. When done, it will sound a bit hollow when tapped and the internal temperature will read 190°F.
Makes 2 loaves.
