Forget the toothpick. That’s for cake. Flan is a custard, so jiggle is your guide.
Gently nudge your flan pan. The center should wobble like Jell-O in a windstorm. The edges should be firm and set.
If the whole thing sloshes like a wave pool, it’s not ready. If it’s stiff as a brick, you’ve killed it.
Why the Center Jiggles
Flan cooks from the outside in. The center stays liquid longer because it’s the last to feel the heat.
That jiggle means the proteins are setting but still have moisture. It’s the sweet spot between custard and scrambled eggs.
Fun fact: The perfect jiggle is called “trembling like a diva” in some professional kitchens. Seriously.
