How to Make Rhubarb Custard Bars: A Step-by-Step Guide
This recipe, when followed exactly as printed, and turned out perfect. The shortbread crust is a delightful counterpoint to the tangy rhubarb custard. If I were to make it again, I wouldn’t change a thing.
- Preheat: Preheat your oven to 375°F (190°C). This ensures the crust bakes evenly and the custard sets properly.
- Make the Crust: In a food processor, combine flour, butter, powdered sugar, and salt. Pulse until the mixture resembles coarse crumbs. The cold butter is key to creating a flaky crust.
- Add Water: Add ice water and pulse until the dough just comes together. Be careful not to overmix, as this can result in a tough crust.
- Press Dough: Press the dough into the bottom of a 9×13 inch baking pan. Ensure an even layer for uniform baking.
- Bake Crust: Bake the crust for 15 minutes, or until lightly golden. This pre-baking ensures the crust is crisp and doesn’t become soggy from the filling.
- Make the Filling: In a large bowl, combine rhubarb, granulated sugar, flour, and cinnamon. The flour helps to thicken the filling, while the cinnamon adds a warm, comforting note.
- Whisk Eggs: In a separate bowl, whisk together eggs, heavy cream, and vanilla extract. This creates a rich and creamy custard base.
- Pour Mixture: Pour the rhubarb mixture over the baked crust. Then, pour the egg mixture over the rhubarb.
- Bake: Bake for 35-40 minutes, or until the custard is set and lightly golden. Keep an eye on the bars to prevent over-browning.
- Cool: Let cool completely before cutting into bars. This allows the custard to fully set and makes for cleaner cuts.
Pro Tips for Perfect Rhubarb Custard Bars
- Use Cold Butter: Cold butter is essential for creating a flaky shortbread crust. Cut the butter into cubes and keep it chilled until ready to use.
- Don’t Overmix: Overmixing the dough can result in a tough crust. Pulse the ingredients in the food processor until just combined.
- Pre-Bake the Crust: Pre-baking the crust ensures that it is crisp and doesn’t become soggy from the filling.
- Use Fresh Rhubarb: Fresh rhubarb is best for this recipe. Look for stalks that are firm and brightly colored. Rhubarb season is short, so take advantage of it!
- Let Cool Completely: Allow the bars to cool completely before cutting into them. This allows the custard to set and makes for cleaner cuts.
Common Mistakes to Avoid
- Overmixing the Dough: Overmixing can lead to a tough crust.
- Not Pre-Baking the Crust: This can result in a soggy bottom.
- Using Warm Butter: Warm butter will create a greasy crust.
- Overbaking the Custard: This can result in a dry and cracked custard.
- Cutting the Bars Too Soon: Cutting the bars before they are fully cooled can result in a messy dessert.
