Blueberry Bagels 2

Today, I tried to bake some blueberry bagels again. I mixed the blueberries into the dough before kneading it this time. The blueberries were squished and so the dough became purple.
I waited for the dough to become two times bigger during rising.
After I boiled the dough, I baked them. They looked a funny colour.
There wasn't much blueberry taste when I tried one so I think it is not a good way to make blueberry bagels.
