To put it bluntly: Despite a very promising rise, the Hybrid Sourdough Challah was a letdown, flavourwise. Drat, drat, drat! Nobody spit it out, but nobody said "mmm" either. The loaves were truly gorgeous, but the bread tasted overly dry and the flavour was bland, to say the least. Not enough salt, not enough sugar, not enough ANYTHING. Maybe that's because I had a cold and couldn't taste it...? Anyway, it wasn't Happy Bread, which puts me back at the drawing board, sourdough-wise. I will climb this mountain, but I think that for Rosh Hashanah and the other holidays coming up, I'd better back off and go back to my regular " challah" recipe. (which is just plain bread with a bit of extra sugar added) Technically, any bread can be called "challah" if it has a small portion taken from the dough which is set aside, a remnant of the ritual in the Jerusalem Temple? We don't feed it to the priests anymore ...
