Frequently Asked Questions

→ Can I make the crust beforehand?
Sure, the crust can be prepared a day earlier and stored in the fridge. It actually becomes easier to roll out after resting.
→ Can I substitute the mustard?
Feel free to swap in other types of mustard. Whole grain mustard adds texture, while a mild mustard gives a softer flavor.
→ How do I keep the crust from getting soggy?
Pre-baking the crust is key. It helps ensure the crust stays firm and crisp under the filling.
→ Can I freeze this pie?
Absolutely! Once baked, it freezes well. Just reheat it in the oven to bring back that flaky crust.
→ What type of cream works best?
Thickened cream is ideal as it keeps the filling from being too runny. Light cream works too but yields a slightly less rich texture.
