Strawberry Rhubarb Pie Sauce and pie filling is a perfect summertime treat to have at the ready in your refrigerator. Sweet and tangy and deliciously perfect.
Add chopped strawberries, rhubarb, sugar, lemon juice, lemon zest, cornstarch, salt, and butter into a medium-size pan. Stir to combine and heat over medium to medium-high heat.
Bring the strawberries and rhubarb to a simmer and cook until the sauce has thickened and the rhubarb is soft; 15 to 20 minutes.
