I took advantage of the glorious snow day here in NYC and made my first challah this morning (from Malgieri's How to Bake). While it tastes delicious, it was a little flatter than I had expected. I'll tell you what I did and maybe someone can tell me how to make it higher rather than longer/flatter. This loaf, by the way, was practice for one that I want to make for a shiva call next Tuesday. I want that one to be beautiful and not just delicious!
I shaped three cylinders about 15 inches long and braided them directly onto a sheet pan. Then I left it for the second rise. It rose up slightly, but mostly spread out. By the time it was ready to be baked, it was about the length of the pan. After baking, it really didn't rise upwards and ended up being about 13 inches long (the pan length) and only about 5 or so inches high.
What can I do better? Should I shorten the length of the three cylinders?
Thanks in advance!
