makes 6 large or 12 smaller scones; inspired by Noelle Johnson's scones at Studio Coffee Roasters and adapted from my Cream Scones recipe
Preheat oven to 400° F. Mix together the dry ingredients in a medium mixing bowl. Add the butter pieces and use a pastry blender (or your fingers) to cut in the butter until mixture is pebbly.
Using a fork, combine ricotta and cream in a glass measure or bowl, whisk in the egg, and pour over flour and butter. Mix with fork until dough just comes together, adding additional cream if it is too dry. Knead in the bowl until the dough just comes together then gently incorporate the berries.
Turn out onto smooth work surface and either pat into one round about 1.5-inches thick for large scones, or divide in half and pat into two rounds for smaller scones.
Cut round into 6 pieces (press straight down with bench scraper or chef's knife) and transfer to a parchment or silpat lined baking sheet spacing each scone apart from its neighbors. Spoon glaze over each scone.
Bake large scones for 25–28 minutes, small scones for 18–20 minutes, until tops are golden. Let cool 5 minutes on pan then transfer to a cooling rack.
