I haven't done an exhaustive study, but I'm going to have to go with the scones at Foxfire Teas, 4605 NE Fremont Street. Apparently, they have tea, too.
The standard bad scone (found locally at Starbucks, Three Lions, Marsee, etc.) is way too heavy or dry. Who really wants to eat a brick for breakfast? Another risk is oversweetness, such as a sticky maple frosting, a half inch layer of lemon glaze, or chocolate chips. Ick.
The proprietress at Foxfire makes them light yet dense, with just the right balance between cake and bread. They are not gut-bombingly big, and if you get there before 10 am, usually warm. Wow. Later in the day, I once got a ham and cheese sandwich from their deli case and it had the same execution: simple, with a lot of attention to detail like a fresh roll, good-quality cheese, briny ham, etc.
Honestly, I love this place. The owners are super friendly, the space is high-design industrial chic, but comfy at the same time, there is a fireplace, wi-fi, and a small corner for kids to romp. I worry because the space doesn't have a street presence, and it's not immediately apparent where the entrance is. A tough retail location. I hope they do well.
Any one have another nominee for best scone?
