In a separate bowl, mix all flours, rosemary, garlic powder and salt. Add the liquid and combine. Empty the dough out on to a well floured surface (the dough at this point should still be very sticky). The key to good bread (in my opinion, any way) is only using just enough flour - too much will result in dry bread. This is even more important when you are making denser breads, such as this one. If you need more flour, add a little additional wholemeal a touch at a time.
