I just made it using all the the optional ingredients but I didn’t have a food processor so I whipped/mixed everything by hand. One thing I noticed is that the top of the bread cracked unevenly. Could I have over fluffed the egg whites? Maybe creating an artificial cut in the middle could solve that next time? It rose very well and nearly doubled in size, though the size is still a bit small for my liking. I will most likely use 1.5x the amount next time. It smells great and I’m about to chow down on this!
