3 cups sliced rhubarb
1 cup quartered strawberries
3 large eggs
pinch of fresh nutmeg
3 tbsp milk
3 tbsp all-purpose flour
1 1/2 cups sugar
*I didn’t mention, but I added a very tiny pinch of salt
1 tbsp butter for "dotting"
pie dough for one 9-inch crust
For the glaze:
2 tbsp jam with 1/4 tsp water, warmed in microwave
Preheat oven to 350 degrees F (175 degrees C). Place rolled-out pie crust in a 9-inch pie plate and set on a baking sheet lined with parchment paper or a silicone baking mat.
Combine rhubarb and strawberries in a bowl; transfer to the pie crust, distributing evenly.
Whisk eggs, sugar, milk, flour, and nutmeg together in a medium bowl. Slowly pour filling over rhubarb mixture until it just reaches the top edge of the crust. Scatter diced butter evenly over the top of the filling. Lightly tap and shake the baking sheet to remove any air bubbles.
Transfer pie to the preheated oven and bake, turning halfway through, until rhubarb is tender and custard is set, about 1 hour.
Mix strawberry jam and water in a small bowl; heat in the microwave until warm, about 15 seconds. Glaze the top of the pie with the jam mixture and let cool. Refrigerate until ready to serve.
