Now you can see how professional they look with their smooth, even sides.
It takes effort, but the results are worth it.
Remarks
This method can be used with other kinds of tart pastry: shortcrust, sweet, etc.
A possible variation is to put the side band in first, then the base circle. This is the opposite way round and a little trickier, but gives a perfect edge around the base after baking.
The glaze applied in stage 18 has two functions: it gives a better colour, of course, but also protects the bottom of the tart from moisture in the filling, avoiding the need to seal the pastry with chocolate (chablonnage).
