Bread-Bakers v102.n038.20

Hi,
I just made the wholewheat bread from the 'Bread Bakers Apprentice'. It was 
delicious. There was one problem though-the dough rose to fill about half 
the loaf pan.

The recipe was for two loaves but I halved the recipe because i wanted to 
try one loaf. Any suggestions/ideas to remedy would be wonderful.

Thank You very much
Uma
