A (or perhaps the?) defining characteristic of Tuscan bread is its lack of salt. I have made saltless Tuscan bread before, and I was pleasantly surprised by its sweet flavor.
This “dark Tuscan bread”, a 70%-whole-wheat version adapted from Carol Field’s The Italian Baker, did not warm my heart quite as well, but I did like the soft crumb and crisp crust. I might experiment with different wheat flours to see how the flavor varies with each. And in fairness, I have to say I have so far only eaten it pretty much straight up, and Tuscan bread is meant to go with the hearty flavors of Tuscan food. Panzanella (tomato and bread salad) is traditional with this bread… stay tuned.
