This was my Grandmothers recipe, we all love it! You can adjust the sweetness by the amount of strawberries you add. You will need 3 cups of fruit in total, but if you want a more tart pie, use more rhubarb than strawberries. I have posted this with exactly 1/2 and 1/2.

I also skipped out on the crust and added 1/4 cup oatmeal to the topping. My boyfriend said it is one the best desserts I’ve ever made! He made me promise to make more immediately :)I used palm sugar instead of sugar, as I have blood sugar sensitivities ..
Excellent pie!!! Delicious!!! We loved it! At first if not completely chilled it was a little loose,but firmed up later and was most yummy!!! I will definitely make this again and again and again!!! I made this for the Farm Women Cooking with Andi of Longmeadow Farm! Woo hoo Andi!! This one is a keeper! Jelly ?

Ingredients

• 1 (9 inch) unbaked pie crust (see footnote for recipe link)
• 3 cups rhubarb, sliced 1/4-inch thick
• 1 cup fresh strawberries, quartered
• 3 large eggs
• 1 1/2 cups white sugar
• 3 tablespoons milk
• 3 tablespoons all-purpose flour
• 1/4 teaspoon freshly grated nutmeg
• 1 tablespoon butter, diced
• 2 tablespoons strawberry jam
• 1/4 teaspoon water

Directions

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.
