FRC--Crostata or Galette or Tart? I found this article after Goggling==>
You've probably noticed, there are a number of names tossed around when comes to baking fresh fruit into a buttery-delicious crust. Some of the most commonly
used (and used interchangeably) are crostata, galette, and tart. And even though the three desserts associated with each title share quite a bit in common, it’s important to draw what line there is to be drawn between them.
Crostata
This rustic dessert consists of a rolled out piece of dough (typically flour, sugar, butter, salt, and water) which is then piled up with fruit (or veggies...savory crostatas are real, and really tasty!) in the center. The edges of the dough are folded in about an inch or so to create crust, and they usually get an egg wash and some coarse sugar on top. These babies are free-form, so they’re cooked on a flat sheet, and no two will look the same. That simple, unpolished look is what makes this dessert so effortless and charming.
Galette
So, we know that we implied that these desserts are not all the same, but when it comes to crostatas and galettes, the only difference is linguistic. Crostata is an Italian term, and galette is French; however, by definition, you can use these terms interchangeably. They’re referring to the same, easy and distinctly elegant dessert. By whichever name, this free-form pastry is always a great choice when you find yourself with a bounty of peak season produce.
Tart
Okay, this one is actually a little different from the other two. What defines a tart is the pan in which it is baked (intuitively named a tart pan). Depending on the style of the pan, a tart can be made in the shape of a rectangle, square, or circle, and they vary vastly in size and in depth (although most are typically quite shallow). The beauty of a good tart pan is that the bottom is removable, so unlike pies, tarts are usually served unmolded from the sides of
the pan–you know, like the way you’d serve a cheesecake that was baked in a springform pan. Thus, you end up with a stunning, free-standing dessert with pretty fluted edges and one that’s worthy of perching on your favorite cake stand. In order to release from the pan without damage, tart crusts will often be a bit more shortbread-like, as opposed to the flakey pie dough typically used for
crostatas and galettes. And, like crostatas and galettes, these can go either savory or sweet, and we certainly do not discriminate here.
