1 tbsp active dry yeast
1/4 cup warm water (approx 110F)
1 1/4 cups buttermilk, room temperature or a bit warmer
1/4 cup honey
2 tsp salt
2 tsp cinnamon
1 cup whole wheat flour
2 - 2 1/2 cups white whole wheat flour
2/3 cups raisins
In a large bowl, combine yeast and warm water. Let stand for 5-10 minutes until foamy.
Mix in buttermilk, honey, salt, cinnamon and whole wheat flour. Stir well. Gradually mix in white whole wheat flour, stirring with a wooden spoon until dough pulls away from the sides of the bowl. Turn out onto a lightly floured surface, adding a bit more flour as you go to keep it from sticking, and knead until smooth and elastic, about 5-7 minutes (it won't get quite as smooth as breads made with other flours, but it will still be a bit stretchy). Place in a lightly greased bowl and cover with plastic wrap. Let stand for 1 1/2 - 2 hours, until doubled in size.
Preheat oven to 375F.
Turn bread out onto a lightly floured surface and gently deflate. Shape into a rectangle, then form into a log by folding the short ends into the center, then pulling the long ends up and pinching them together. Place dough seam-side down into a greased 8x4 inch loaf pan. Let rise for 45-60 minutes.
Bake at 375F for 35-40 minutes (until an internal-read thermometer inserted into the bottom of the loaf reads approx 200F). Remove from pan and cool completely on a wire rack before slicing and toasting.
Makes 1 loaf.
