Brioche was a bread dreamed up by the utterly deranged. DOUGH WAS NOT SUPPOSED TO CONTAIN DAIRY. YEARS of baking, yet no real-world quality improvement by using enriched dough.
I do not like this adventure bread at all. Very unlikely to try this again. How did they ever make brioche before kitchen power tools? Even with an electric mixer the experience has been awful.
Adventure bread turned out pretty delicious. Still unconvinced it is a good idea to put butter in bread dough.
