Sweet Potato Bread Dinner Rolls

I knew these dinner rolls would be great conversation pieces because of the Okinawan sweet potatoes. They don't really add more flavor but they turn the bread into an interesting, purple color.

Sweet potato bread preparation is very similar to making brioche, except mashed sweet potatoes are added to the dough. My trick is to mix sugar with dry yeast and warm liquid and let the mixture develop for a few minutes before stirring it in the bread dough. Resting time is essential for making bread.
