Rhubarb Applesauce Pie

Applesauce is the unsung hero in this rhubarb pie. Three-quarters of a cup adds natural fruit sweetness and gentle apple flavor that takes the edge off rhubarb’s sharp character without requiring a mountain of refined sugar. The applesauce also acts as a body builder, contributing pectin that helps the filling set thick and glossy rather than runny.

Quick-cooking tapioca is the right thickener choice over flour or cornstarch. It produces a clear, bouncy filling that holds clean slices and shows off the rhubarb pieces suspended throughout. Three tablespoons is enough for the volume of liquid the rhubarb releases. Less and the pie weeps; more and the filling gets gluey.

The lattice top is more than decoration. Rhubarb pies bubble vigorously during baking, releasing significant juice. The lattice gives steam an exit so the filling reduces and concentrates rather than steaming the crust soggy. Place the pie on a cookie sheet because it will overflow.

Pro Tips

• Use unsweetened applesauce. Sweetened versions throw off the sugar balance and make the pie cloying.
• Let the filling sit 10-15 minutes after mixing before pouring into the crust. This lets the tapioca begin absorbing liquid.
• Cut rhubarb into ½-inch pieces. Smaller pieces disappear into the filling; larger ones stay too firm.
• Let the pie cool 2-3 hours before slicing. Hot rhubarb pie filling slumps and turns gloppy.

Variations

• Use chunky applesauce instead of smooth for visible apple pieces in the filling.
• Replace ½ cup of rhubarb with sliced strawberries for the classic spring pairing.
• Stir in ¼ cup raisins for chewy texture and extra natural sweetness.
