I made a batch using half wheat, half white flower and it turned out ok. It didn't rise as much as the white did, but it had a decent texture, and the taste was great!
I watched the video again, and my batches just didn't rise much the second time. And after the two hour rise, they still seem to be really "wet" compared to what it looks like in the video. I just think it should rise more during the 2 hours before the oven, and firm up a little bit. Any ideas?
