Frequently Asked Questions
- → Can I make this in advance?
Yes! Assemble it up to a day early, keep it chilled in the fridge, and brush with egg wash right before baking.
- → Why isn’t my pastry rising?
Your pastry might need to be cool but fully thawed. Don’t forget those small cuts on top, and always preheat your oven first.
- → Can I switch up the cheese?
Sure, try Gruyere, Swiss, or any nice melting cheese. Just avoid cheese that's too watery to keep the texture crisp.
- → How do I know it’s baked?
Look for a golden and fluffy top, usually after around 20 minutes. You might hear a faint sizzle from the cheese inside.
- → Can leftovers be frozen?
Absolutely! Wrap securely, freeze for up to 2 months, and reheat at 350°F until warmed through to keep it crispy.
