This is recipe #5 Challah of the Whole Grain Bread book by Peter Reinhart challenge that Jenni started. Here is Jenni's blog: http://somethingtosavor.blogspot.com/2011/05/wgb-challange.html
This recipe uses 4 whole eggs and 1 egg yolk so it is no wonder that it rose wickedly high.
My braiding technique isn't great BUT I'm learning.
Very tasty loaf. I'm loving it.
I ended up adding about 1/2 cup more whole wheat flour and it was still a tad sticky.
