FAQ

Does allulose caramelize like sugar?

Yes — it melts and browns almost identically to sugar without the bitterness or crystallization of other keto sweeteners.

Why not use erythritol or monk fruit blends?

They crystallize after heating and create gritty textures. Allulose keeps flan perfectly smooth.

How long does keto flan last?

Up to 5 days in the refrigerator.

Can I make it dairy-free?

Yes — substitute coconut milk for the cream. Texture will be slightly softer.

Can you freeze flan?

No — freezing causes separation.
