I attempted this recipe for the third time tonight. I love the simplicity of it and how moist and tasty it is but I'm not getting the rise you describe. I am using King Arthur whole wheat flour. I bought a new jar of yeast after the first attempt, thinking my yeast was old. Really no change. Tonight the first and second rise were better but the final proofing in the pan was...well, it barely reached the top of the pan ( also bought the pan from Amazon you recommended thinking it might have been my glass loaf pan). It didn't really oven spring either. Any suggestions would be appreciated. Again, love the texture and the taste...just want it to be a little more like your picture.
