Prep & Cook Time

Ingredients

• Crust
• 1 1/4 cups graham cracker crumbs
• 1/4 cup granulated sugar
• 6 T. butter (melted)
• Pie
• 14 oz. sweetened condensed milk
• 5 large egg yolks
• 1 cup fresh grapefruit juice (2 large grapefruit)
• 1 drop peach gel paste color (optional)

Instructions

1. Preheat your oven to 350°F (175°C).
2. In a medium bowl, mix the graham cracker crumbs and granulated sugar. Pour in the melted butter and stir until the crumbs are evenly moistened and resemble wet sand.
3. Press the crumb mixture firmly and evenly into the bottom and up the sides of a standard 9-inch pie plate. Use the bottom of a flat glass or measuring cup to help create a compact, even crust.
4. Bake the crust for 10 minutes, then remove from the oven and let it cool slightly on a wire rack. Reduce the oven temperature to 325°F (160°C).
5. While the crust bakes, prepare the filling. In a large bowl, whisk the sweetened condensed milk and egg yolks together until completely smooth and slightly thickened.
6. Very gradually whisk in the fresh grapefruit juice until the mixture is homogenous. Add the optional peach gel paste color at this stage and whisk to incorporate, if using.
7. Pour the filling into the slightly cooled, pre-baked crust.
8. Bake the pie at 325°F for 30-32 minutes. The pie is done when the edges are set but the center still has a slight, gentle jiggle when tapped.
9. Remove the pie from the oven and let it cool completely on a wire rack. Once cool, refrigerate for at least 4 hours, or preferably overnight, to fully set before slicing and serving.

Variations

• Chilled No-Bake Method: For a creamier texture, you can skip the final bake. After combining the filling ingredients, pour it into the pre-baked, cooled crust and refrigerate for at least 6 hours until firm.
• Meringue Topping: Use the leftover egg whites to make a Swiss meringue. Toast it with a kitchen torch for a beautiful, classic finish.
• Individual Servings: Press the crust mixture into muffin tins lined with parchment squares to create mini pies. Reduce the baking time for the filling to 18-22 minutes.
• Citrus Zest Garnish: Before juicing, zest one of the grapefruits and sprinkle the fresh zest over the chilled pie just before serving for an extra burst of aroma.

Tips for Success

• Ensure your grapefruit juice is freshly squeezed and strained to avoid any pulp or seeds in the silky filling.
• For the cleanest slices, use a sharp knife dipped in hot water and wiped dry between each cut.
• Don’t overbake the pie. The slight jiggle in the center is key—it will set fully as it chills.
• Let the melted butter cool for a minute before mixing it with the crumbs to prevent the crust from becoming greasy.

Storage & Reheating

Store the pie, covered tightly with plastic wrap or in an airtight container, in the refrigerator for up to 4 days. This pie is meant to be served cold and should not be reheated.

FAQ

Can I use bottled grapefruit juice?

It’s not recommended. Bottled juice often contains preservatives and lacks the bright, fresh flavor essential to this pie.

My filling didn’t set. What went wrong?

The most common causes are underbaking or inaccurate oven temperature. Ensure your oven is fully preheated and use an oven thermometer to check. The pie must be fully chilled to set.

What can I do with the leftover egg whites?

You can make a meringue topping, add them to scrambled eggs or an omelet, or freeze them in a labeled container for future use in angel food cake or macarons.

Can I use a different type of crust?

Yes, a pre-baked traditional pie crust or a shortbread cookie crust would also work well with this filling.

Why is the color optional?

The egg yolks and condensed milk create a pale yellow filling. The single drop of peach gel color (not liquid food coloring) gently mimics a beautiful grapefruit blush without altering the flavor.

Can I use another citrus fruit?

This recipe is specifically calibrated for grapefruit juice, which is less acidic than lemon or lime. Substituting a more acidic juice may cause the filling to curdle or not set properly.
