Strawberries and rhubarbs come together with a golden brown biscuit to form a new type of shortcake. Whipped cream and optional limoncello make these fruit flavors shine!
Stir together rhubarb, sugar, limoncello, and cornstarch in a saucepan just until the cornstarch dissolves. Bring to a simmer over medium heat. Cook, stirring, until the rhubarb is softened and the mixture is slightly thickened, 6-8 minutes. Remove from the heat and stir in the strawberries.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
2 cups all-purpose flour, 1 tbsp baking powder, 1 tsp baking soda, ¼ cup granulated sugar, ½ tsp kosher salt
Cut butter into tablespoon-size pieces and stir into the flour mixture to coat the butter with the dry ingredients. Using a pastry cutter or hands, cut in the butter until the mixture becomes like coarse, wet sand. The mixture should hold together when squeezed and then crumble away.
8 tbsp (1 stick) unsalted butter
In a small bowl, whisk together the buttermilk, egg, and vanilla extract. Pour in the flour mixture and quickly stir with a fork.
⅔ cup buttermilk, 1 large egg, 1 tsp vanilla extract
When the mixture begins to hold together and is very shaggy, pour it onto a floured surface. Knead together until a dough is formed. Then press into a 7x10-inch rectangle about ½ inch thick. Fold into thirds, then press into a 5x7-inch rectangle about 1 inch thick.
Cut dough into 8 biscuits and arrange 1 ½ inches apart on a parchment-lined baking sheet. Brush with heavy cream and sprinkle with turbinado sugar.
1 tbsp heavy cream, 2 tsp turbinado sugar
Bake in preheated oven until golden, 12-14 minutes. Remove from oven and cool for 15 minutes on a wire rack.
To serve, slice a biscuit in half and spoon the fruit on the bottom half. Place biscuit on top and dollop with whipped cream.
