7: Bake for 15-20 minutes. Remove paper and beads.
8: Pour the mixture into the pastry base.

Baking the flan
And bake in the oven for 20-30 minutes, keeping an eye on the color of the pastry.

Remarks
To accentuate the sesame aspect, you can add a few roasted sesame seeds when you prepare the shortcrust pastry. For decoration, you can also sprinkle the top of the flan with a few white sesame seeds, for a black-and-white contrast.
