This sauce can be made 2 days ahead and refrigerated in an airtight container. Reheat over medium-low heat, or bring to room temperature before serving.

Ingredients

　　12 ounces rhubarb (6 to 8 stalks), trimmed and cut into 1-inch pieces

　　6 tablespoons sugar

　　1 1/2 cups strawberries (8 ounces), hulled and halved

　　1/2 teaspoon pure vanilla extract

　　Bring the rhubarb, sugar, and 1/4 cup water to a simmer in a medium saucepan over medium-high heat, stirring occasionally. Cook until the liquid is reduced by half, about 8 minutes. Stir in the strawberries and vanilla; cook until the berries are softened, about 3 minutes more. Serve the sauce warm or at room temperature.
