First is a basic twist on the recipe: add walnuts. I think the crease in the top happened when I turned the bread out, possibly before it had cooled enough. >-< But it tasted good. I made sure to sprinkle nuts on top of the dough before it cooked so people were aware of what was inside.
Next is banana bread with shredded coconut inside. I was actually one banana short when making this bread, so I figured the extra coconut would give the bread the support it needed. Before baking it, I toasted some reserved coconut and sprinkled it on top of the dough. This one also came out pretty good, but I don't think the flavors were as strong as the others.
For this last one, I added the zest of three oranges to the dough and baked it. The result was banana bread with a very aromatic orange flavor to it. Banana was the primary flavor, but orange was a more subtle undertone. All of the breads were met with great appreciation and critical acclaim, so I felt I had done a good job.
