Spread 200 g
Sweetcrust pastry (pâte sablée) lengthwise, not too thinly (you need a nice crust after baking) and
pour the pan.
I'm using a full-length pie tin here, but if you don't have one, a cake tin will do, just leave only 2 cm or 1 inch of pastry height around the edges.
Put on standby in the fridge, leaving the pastry sticking out well as in the photo (important).
