Frequently asked questions
+ − Can I make krempita with homemade pastry?
Yes, but puff pastry requires significant skill and time to make from scratch. Store-bought puff pastry gives excellent results and saves hours of work.
+ − Why is my custard lumpy?
Lumpy custard usually occurs from cooking too quickly or not whisking constantly. Always use medium heat and whisk continuously. If it happens, strain the custard through a fine mesh sieve.
+ − How do I prevent soggy pastry?
Make sure both pastry layers are completely cooled before assembling, and bake them until deeply golden. The contrast in temperature between warm custard and cool pastry also helps maintain texture.
+ − Can I prepare this dessert ahead of time?
Absolutely! Krempita actually improves after chilling overnight as the flavors meld and the custard sets perfectly. Just add the powdered sugar right before serving.
