Ingredients
Scale
Filling
- 1 cup Ruby Red Grapefruit Juice (Fresh is key for maximum taste.)
- 1 cup Granulated Sugar (Sweetens the filling.)
- 1 tbsp Fresh Lemon Juice (Substitute with about 1 medium lemon if needed.)
- 2 Eggs (Adds richness.)
- 1 large Egg Yolk (Binds the filling.)
- 1/2 cup Unsalted Butter (Infuses richness.)
- 1/4 cup All-Purpose Flour (Provides necessary structure.)
- 1/4 tsp Kosher or Sea Salt (Enhances flavor.)
- Zest of Ruby Red Grapefruit (Implied in instructions for extra flavor)
Crust
- 1/2 cup Unsalted Butter (Use cold for best results.)
- 1/4 cup Granulated Sugar (Sweetens the crust.)
- 1 cup All-Purpose Flour (Essential structure for the crust.)
- 1/4 tsp Kosher or Sea Salt (Elevates flavors.)
Finishing
- 1 tbsp Confectioner’s Sugar (Dust before serving.)
- 1 Red Food Coloring (Optional for visual appeal.)
Instructions
- Preparation: Preheat your oven to 350°F (175°C). Line an 8- or 9-inch square pan with foil and lightly grease it with butter to prevent sticking.
- Reduce Grapefruit Juice: Zest and juice the grapefruits. Pour 1 cup of fresh grapefruit juice into a saucepan and heat over medium-high heat. Allow it to reduce by half to about ½ cup, which takes approximately 10-12 minutes. This reduction intensifies the grapefruit flavor for the filling.
- Make the Crust: In a mixing bowl, combine 1 cup all-purpose flour, 1/4 cup granulated sugar, and 1/4 teaspoon kosher or sea salt. Cut in 1/2 cup cold unsalted butter until the mixture resembles coarse crumbs. Press this dough evenly into the bottom of the prepared pan. Bake the crust in the preheated oven for 10 minutes until lightly golden.
- Prepare the Filling: In another bowl, whisk together the grapefruit zest, 1 cup granulated sugar, the reduced grapefruit juice, 1 tablespoon fresh lemon juice, 2 eggs, 1 large egg yolk, 1/2 cup melted unsalted butter, 1/4 cup all-purpose flour, and 1/4 teaspoon kosher or sea salt until the mixture is smooth and well combined.
- Assemble and Bake: Pour the prepared grapefruit filling over the cooled crust and smooth the top. Bake the bars for 18 to 20 minutes, or until the filling is set and the edges are slightly firm.
- Cool and Chill: Remove the pan from the oven and let the bars cool completely on a wire rack. Once cooled, place the bars in the refrigerator and chill for at least 4 hours to allow the filling to fully set.
- Serve: Before serving, dust the bars with 1 tablespoon of confectioner’s sugar for a delicate finish. Optionally, add a drop of red food coloring to the dusting sugar for visual appeal.
Notes
- Ensure the grapefruit juice is fresh for the best flavor; bottled juice will not yield the same brightness.
- Reducing the grapefruit juice intensifies the flavor and prevents the filling from being too runny.
- Chilling the bars overnight or for at least 4 hours helps the filling to firm up properly.
- Use cold butter when making the crust to achieve a tender and crumbly texture.
- The red food coloring is optional and intended only for aesthetics; omit if preferred.
- You can substitute kosher salt with sea salt if that’s what you have on hand.
- Store refrigerated and consume within 3-4 days for optimal freshness.
