I did KAF Apple Challah bread Friday, leaving out the sugar and using all whole wheat flour. I thought it appropriate for New Year's celebration since the Jewish New Year stars apples and honey. I had to leave out the honey and sugar. I took it to a Science Fiction Club meeting, the hostess likes it because it doesn't have any sugar. I baked it in a slow cooker for three hours until it was 190 degrees. Came out very nicely.
