I put some orange zest in the bread and made an orange glaze for the top. Turned out great using the original recipe! I think without the glaze it would not be sweet enough for most people's taste. However if I wasn't bringing this to a potluck and was eating it myself, I would leave it at the lower amount of sugar. Tastes perfectly good.
I made this recipe exactly the original and the results were not good. I hope you test the recipes before publish them I was very disappointed.
To get it to rise a bit better, I used 2 C ww flour, 1/2 C almond flour and butter creamed with the sugar. Also, for guests I increased the sugar to 1/2 C because most people require a sweeter quick bread. I used real diced cranberries. This is an extremly moist, healthful bread!
