Tarte au sucre — northern French raised sugar tart
Northern French tarte au sucre is easy to misread if the name is taken literally. It is not a Canadian-style sugar pie with a syrup custard. The French form is built on an enriched yeast dough, baked low and round like a shallow brioche, with sugar and butter concentrated on the surface.
Vergeoise gives the topping its regional character. The soft beet sugar melts into the fingertip dimples together with small pieces of butter, creating pockets of caramelised sweetness while the crumb stays airy. Cream goes on only after the main bake and returns to the oven briefly, so it soaks into those wells rather than becoming a separate custard layer.
The two rises are not optional waiting time. The first gives the dough body and gas; shaping knocks some of that out, so the second rise rebuilds a light structure in the tin. Dimpling must be gentle enough to preserve that lift. The finished tart is best after a short cool, when the topping has settled but the crumb is still warm and supple.
