How to Perfect Lemon Crumb Bars

Common Mistakes to Avoid
When making Lemon Crumb Bars, it’s easy to overlook a few key steps. Here are some common mistakes and how to avoid them.
- Ignoring Room Temperature Ingredients: Make sure your egg yolks and heavy cream are at room temperature to help the filling blend smoothly.
- Overmixing the Crust: Mix the crust ingredients just until crumbly. Overmixing can lead to a tough texture.
- Skipping the Cooling Step: Letting the bars cool completely before refrigerating is crucial for a firm set. Skipping this step can result in runny bars.
- Not Using Fresh Lemon Juice: Always use fresh lemon juice for the best flavor. Bottled lemon juice can lack the vibrant taste of fresh lemons.
- Cutting Too Soon: Be patient and wait at least 4 hours before slicing your bars. This allows them to firm up properly.
