Frequently asked questions
Can I use vanilla sugar or vanilla extract?
While a natural vanilla bean is ideal for authentic flavor, you can use vanilla extract or vanilla sugar by adjusting the quantities according to the desired intensity.
How do I know when the flan is done baking?
The flan is ready when the surface is lightly browned and the center feels firm to the touch. It may still jiggle slightly, but it will firm up as it cools.
Can this crustless flan be frozen?
Freezing the flan is not recommended as it can negatively affect the texture. It is best enjoyed fresh or kept in the refrigerator.
