Maple Yogurt Multi-grain Rolls

Spring is finally here so it was time to make some rolls to use for grilled burgers. I used a mix of fresh milled spelt and whole wheat along with some KAF bread flour.
I wanted to see if I could get some maple flavor in these so I added a dark 100% maple syrup in the levain and in the main dough. Well, that achieved nothing except making the levain triple in size from the natural sugars in the syrup. It did add a nice sweetness to the rolls but not enough to be over the top.
