These are the perfect summer muffin, delicious and pretty, with a juice-stained golden crumb. In berry season, make several batches of these; then freeze the overrun. You will be happy you did, especially when the season, so short-lived, has come and gone. Luxe as is, these become decadent with a dab of mascarpone on top. And don't limit them just to breakfast. They are special any time of day.
