During the school year all my kids ever wanted for breakfast was some kind of pastry. I really wanted to try and make them myself AND make something sourdough!
I found this recipe: Sourdough Blueberry Brioche Tarts - Made in Motherhood
Its a little time consuming, but generally as much as sourdough making seems to go. This recipe uses blueberries, but my husband hates blueberries, so I used blackberries instead. They were absolutely delicious!
