Ingredients

Here is what you’ll need for the Rhubarb Custard Pie:

  • 2 ½ cups unbleached all-purpose flour
  • ½ teaspoon kosher salt
  • 2 sticks butter, chilled and cubed
  • ½ cup cold water
  • 1 egg
  • 1 tablespoon white vinegar
  • 4 cups fresh rhubarb (1 pound or 450g), sliced ¼ inch thick
  • 1 cup granulated sugar
  • 3 tablespoons unbleached all-purpose flour
  • ½ teaspoon kosher salt
  • 1 cup 35 percent cream
  • 1 teaspoon vanilla extract
  • ½ teaspoon almond extract
  • 3 large eggs, room temperature
  • Icing sugar for garnish (optional)
  • Whipped cream for garnish (optional)

Fresh rhubarb is key to delivering vibrant flavor; if you can’t find it, frozen rhubarb can be a suitable alternative, but be sure to thaw and drain it thoroughly. The use of 35 percent cream adds a rich, luxurious texture that makes the custard smooth and heavenly.

Ingredient Notes and Easy Substitutions

  • Flour: You can replace unbleached all-purpose flour with whole wheat flour for a nuttier flavor, but the texture may differ slightly.
  • Butter: Unsalted butter is recommended to ensure you control the saltiness. If you’re in a pinch, margarine can be used but may alter the flavor.
  • Rhubarb: If rhubarb is out of season, consider using strawberries or blueberries mixed with some lemon juice for a delicious fruit mix.
  • Cream: Substitute half-and-half for a slightly lighter custard, or use coconut milk for a dairy-free option while still achieving a rich flavor.

Instructions

1. Prepare the Pie Dough:

In a small bowl, whisk together the egg, vinegar, and cold water; set aside. In a medium bowl, stir together the flour and salt. Add the chilled butter and rub it into the flour until it resembles small pea-sized balls. Drizzle the egg mixture over the flour mixture and mix by hand until fully combined. Divide the dough, wrap it in plastic wrap, and refrigerate for at least 2 hours.

2. Assemble and Bake the Pie:

Preheat your oven to 350°F (175°C). Roll out one disc of chilled dough into a pie plate, ensuring it covers the edges well. Evenly arrange the sliced rhubarb in the pie shell. In a measuring jug, whisk together granulated sugar, 3 tablespoons of flour, salt, cream, vanilla extract, almond extract, and eggs until well blended. Pour the creamy mixture over the rhubarb.

3. Bake the Pie:

Bake the pie for about 50 minutes, rotating halfway through. The custard should be set but jiggle slightly in the center when done. Allow it to cool completely before slicing. Dust with icing sugar and serve with whipped cream if desired.

Expert Tips for the Best Results

  • Chill Everything: Make sure your butter and water for the pie crust are cold; this helps create a flaky texture.
  • Don’t Overmix the Dough: When combining the wet and dry ingredients, mix just until combined to prevent a tough crust.
  • Check for Doneness: Keep an eye on the pie during baking; if it starts to brown too quickly, cover it loosely with foil.
  • Let it Cool: Allow the pie to cool completely before serving; this will enhance the flavors and improve the custard’s texture.

Variations

  • Berry Rhubarb Custard Pie: Add a cup of mixed berries for a fruity twist that pairs wonderfully with rhubarb’s tartness.
  • Nutmeg Spice: Introduce a hint of nutmeg or cinnamon to the custard for added depth.
  • Coconut Cream: Replace some of the heavy cream with coconut cream for an exotic and tropical flavor.
  • Mini Pies: Use a muffin tin to create individual servings, adjusting baking time accordingly.
  • Graham Cracker Crust: Use a graham cracker crust for a simple, no-roll option that adds a sweet buttery flavor.

Serving Suggestions

The Rhubarb Custard Pie can be served warm or chilled and pairs exquisitely with:

  • A scoop of vanilla ice cream
  • A dollop of freshly whipped cream
  • A light sprinkle of fresh mint for a pop of color and flavor
  • Serve alongside a cup of warm tea or coffee for a delightful afternoon treat.

Storage and Reheating

Store leftover pie in the refrigerator covered with plastic wrap or in an airtight container for up to 3 days. Reheat slices in a preheated oven at 350°F (175°C) for about 10 minutes or microwave in 15-second intervals until warmed.

If you plan to make it ahead of time, consider preparing the pie crust and filling separately; assemble it just before baking for the freshest taste.

Common Mistakes to Avoid

  • Using Warm Ingredients: Ensure that your butter is cold for the best crust.
  • Overbaking: Keep an eye on the pie; overbaking can lead to a rubbery custard.
  • Not Letting it Cool: Skipping the cooling step before slicing can result in a messy pie.

FAQ

1. Can I use frozen rhubarb?

Yes, frozen rhubarb works well. Be sure to thaw it and drain excess moisture before using.

2. Can I substitute the cream?

Yes, half-and-half or coconut milk can be used for a lighter or dairy-free option.

3. How long does the Rhubarb Custard Pie last?

It can be stored in the refrigerator for up to 3 days.

Absolutely! You can prepare the pie dough in advance and refrigerate it for up to 2 days before use.

5. What is the best way to serve the pie?

It’s delicious either warm or chilled. A scoop of ice cream or a dollop of whipped cream enhances the flavors beautifully.
