Blackbird Doughnuts

This South End shop helpfully explains the differences between its two styles of donuts: raised (made with a brioche dough) and cake (made with buttermilk and sour cream). Keep an eye out for offbeat flavors such as sesame sriracha, blackberry lavender, and everything bagel (brioche doughnut filled with whipped cream cheese, topped with toasted garlic, onion, sesame, and poppy seeds).
