Semifreddi’s makes a divine, eggy, soft challah with a little extra sugar in the dough and cinnamon worked into the braids. Actually, Cinnamon Twist isn’t exactly bread, it’s cake — just the kind of nourishment Marie Antoinette might have approved for the rabble. You can certainly feel like royalty in the morning with a couple of slabs of it toasted and drenched in melting butter. They also make a fine toasted accompaniment for midmorning tea. And it’s amazing how many improbable combinations a person can orchestrate just to make cinnamon-flavored sandwiches.
