Ingredients

• 2 cups rhubarb, diced
• 3/4 cup sugar + 1/4 cup sugar
• 2 egg yolks
• 2 tablespoons flour
• 1 teaspoon lemon juice
• 1/4 teaspoon salt
• 1 cup milk
• 1 9-inch pie shell
• 2 egg whites
• 6 tablespoons sugar
• 1/4 teaspoon lemon juice

How to make Rhubarb Custard Pie with Meringue Topping

Step 1: First, prepare the rhubarb. In a medium saucepan, combine the 2 cups of diced rhubarb with 3/4 cup of sugar. The small amount of water clinging to the rhubarb after rinsing is enough to get it started. Bring the mixture to a boil over medium heat, stirring occasionally. Once it boils, reduce the heat and let it simmer for about 7 minutes, or until the rhubarb is tender. Remove it from the heat and set it aside to cool down.

Step 2: Preheat your oven to a hot 450° F. While the rhubarb cools, get started on the custard. In a mixing bowl, add the 2 egg yolks, the remaining 1/4 cup of sugar, 2 tablespoons of flour, 1/4 teaspoon of salt, and 1 teaspoon of lemon juice. Beat these ingredients together until the mixture is smooth and creamy.

Step 3: Gradually add the 1 cup of milk to the egg yolk mixture, beating continuously until everything is well combined. Gently stir in the cooled, cooked rhubarb. Pour this beautiful, pink-flecked custard filling into your unbaked 9-inch pie shell.

Step 4: Carefully place the pie in the preheated 450° F oven and bake for 10 minutes. This initial high heat helps set the crust. After 10 minutes, reduce the oven temperature to 325° F and continue baking for another 25 minutes. The custard should be thickened and mostly set.

Step 5: While the pie is finishing its bake, make the meringue. In a clean, dry bowl, beat the 2 egg whites until they form stiff peaks. You’ll know they’re ready when you can lift the beater and the peak holds its shape without flopping over. Gradually add the 6 tablespoons of sugar while continuing to beat, which will create a glossy, stable meringue. Beat in the final 1/4 teaspoon of lemon juice.

Step 6: Remove the pie from the oven. Reduce the oven temperature one last time to 300° F. Spoon the finished meringue over the hot custard, spreading it to the edges of the crust to seal it. Use the back of a spoon to create lovely swirls and peaks. Return the pie to the 300° F oven and bake for an additional 15 minutes, or until the meringue is a beautiful light golden brown. Let it cool before slicing.

How to serve Rhubarb Custard Pie with Meringue Topping

This pie is best served chilled, which allows the custard to fully set for clean, beautiful slices. Let it cool on the counter for about an hour before transferring it to the refrigerator for at least 4 hours. Serve it as is, or with a dollop of whipped cream for extra decadence. It’s the perfect sweet ending to a family dinner or the star of a spring potluck.

How to store Rhubarb Custard Pie with Meringue Topping

Meringue pies are notoriously tricky to store, as the meringue can weep or become soft. For best results, this pie should be eaten the day it’s made. If you have leftovers, store them in the refrigerator. To protect the meringue, you can gently cover it by sticking toothpicks around the pie and loosely draping plastic wrap over them, trying not to let the wrap touch the meringue. It will keep for up to 2-3 days, though the texture of the meringue will change over time.

Tips to make Rhubarb Custard Pie with Meringue Topping

Meringue Mastery: For a perfect, voluminous meringue, make sure your bowl and beaters are completely clean and free of any grease. Even a tiny speck of egg yolk can prevent the whites from whipping up properly. Beating the whites to stiff peaks before gradually adding sugar is key to a stable meringue.

Don’t Skip the Cooling: Allow the cooked rhubarb to cool before adding it to the custard mixture. Adding hot rhubarb to the egg-based custard could cause it to curdle.

Seal the Edges: When you spread the meringue on top of the pie, make sure it touches the crust all the way around. This creates a seal that helps prevent the meringue from shrinking away from the edges as it bakes.

FAQs About Rhubarb Custard Pie with Meringue Topping

Can I use frozen rhubarb for this recipe?

Yes, you absolutely can! Thaw the frozen rhubarb completely and drain any excess liquid before proceeding with the recipe. You may need to pat it dry with a paper towel to ensure the filling doesn’t become too watery.

Why is my meringue weeping?

Weeping, or when liquid beads form on the meringue, is often caused by humidity or undissolved sugar. Beating the sugar in gradually and making sure it fully dissolves into the egg whites can help prevent this. Baking on a humid day can also contribute to this issue.

Can I make this pie with a pre-baked pie shell?

This recipe is designed for an unbaked pie shell, as the custard and crust bake together. Using a pre-baked shell might result in an over-browned crust due to the total baking time. If you only have a pre-baked shell, you might try covering the edges with foil to prevent them from burning.
