Strawberry and Rhubarb Shortcakes

1 . Stage

Stir together rhubarb, sugar, limoncello, and cornstarch for filling in a saucepan just until cornstarch dissolves. Bring to a simmer over medium heat. Cook, stirring, until rhubarb is softened and mixture is slightly thickened, 6 to 8 minutes. Remove from the heat and stir in strawberries.

2 . Stage

Preheat the oven to 425 degrees F (220 degrees C). Line a baking sheet with parchment paper.

3 . Stage

Whisk together flour, white sugar, baking powder, baking soda, and salt for biscuits in a large bowl. Add butter and stir until coated. Cut in butter with 2 knives or a pastry blender until mixture resembles coarse, wet sand. (It should hold together when squeezed, then crumble away.)

4 . Stage

Whisk together buttermilk, egg, and vanilla in a small bowl; pour into the flour mixture and quickly stir with a fork. When mixture begins to hold together, transfer to a floured surface.

5 . Stage

Knead just until a dough ball forms. Press into a 7x10-inch rectangle about 1/2 inch thick. Fold into thirds, then press into a 5x7-inch rectangle about 1 inch thick.

6 . Stage

Cut dough into 8 biscuits and arrange 1 1/2 inches apart on the prepared baking sheet. Brush with whipping cream and sprinkle with coarse sugar.

7 . Stage

Bake in the preheated oven until golden, 12 to 14 minutes. Transfer to a wire rack. Let cool about 15 minutes.

8 . Stage

Slice biscuits in half; serve with filling and whipped cream.
