• Lightly sweetened and softly whipped cream
To prepare shortcakes: Preheat oven to 425 degrees and line a baking sheet with parchment paper.
In a large bowl, whisk together flour, baking powder, salt and sugar. Drop in butter and, using your fingers, toss to coat pieces of butter with flour. Quickly, working with your fingertips (the author's preferred method) or a pastry blender, rub (or cut) butter into dry ingredients until mixture is pebbly. You'll have pea-size pieces, pieces the size of oatmeal flakes and pieces in between, and that's just right.
Pour cream over dry ingredients and toss and gently turn ingredients with a fork until you have a very soft dough. When dough comes together, you'll probably still have dry ingredients at bottom of bowl -- just use a spatula or your hands to mix and knead dough until it's evenly blended. Don't overdo it; it's better to have a few dry spots than overworked dough. Even with all flour mixed in, dough will be soft and sticky.
