I've finally had enough time to complete the November Daring Baker's Challenge.
Preparing pasta frolla with a food processor takes 10-15 minutes
Preparing pasta frolla without a food processor takes 20-25 minutes
Allow the pasta frolla to chill thoroughly. I recommend at least two hours.
Rolling the pasta frolla and assembling the crostata takes 25-30 minutes, if you use fruit preserves.
Baking the crostata takes about 35 minutes, if you use fruit preserves.
Preparation time for other types of crostata vary. For example, making crostata with pastry cream requires the time to make pastry cream (25-30 minutes) and a longer baking time. If you make crostata with fresh fruit, you'll need time to prepare the fruit, besides the time needed to prepare pastry cream. In this case, you assemble the crostata after the crust is baked.

9 or 9.5-inch [23-24 cm] fluted round tart pan with removable bottom, about 1 inch [2.5 cm] high. (Note: If you don't have a tart pan with a removable bottom, don’t worry! You can make crostata using a 9-inch cake pan or even a 9-inch pie plate. See the Additional Information section for information on using different pans.
a food processor is useful, but not required
Ingredients:
1/2 c. minus 1 tablespoon [105 ml, 100 g, 3 ½ oz] superfine sugar (see Note 1) or a scant 3/4 cup [180ml, 90g, 3 oz] of powdered sugar
1 and 3/4 cup [420 ml, 235 g, 8 1/4 oz.] unbleached all-purpose flour
a pinch of salt
1 stick [8 tablespoons / 4 oz. / 115 g] cold unsalted butter, cut into small pieces
grated zest of half a lemon (you could also use vanilla sugar as an option, see Note 2)
1 large egg and 1 large egg yolk, lightly beaten in a small bowl
Note 1: Superfine sugar is often also referred to as ultrafine, baker’s sugar or caster sugar. It’s available in most supermarkets. If you cannot find “superfine” sugar, you can make your own by putting some regular granulated sugar in a food processor or blender and letting it run until the sugar is finely ground.
Note 2: There are different ways of making vanilla sugar. I keep vanilla beans in a jar half-filled with sugar until I need to use them, for example, to make vanilla ice cream. After I remove the split bean from the custard that will go into the ice cream maker, I rinse it, dry it and put it back in the jar with sugar.
Making pasta frolla by hand:
Whisk together sugar, flour and salt in a bowl.
Rub or cut the butter into the flour until the mixture has the consistency of coarse crumbs. You can do this in the bowl or on your work surface, using your fingertips or an implement of choice.
Add the lemon zest to your flour/butter/egg mixture.
Knead lightly just until the dough comes together into a ball.
Shape the dough into a flat disk and wrap in plastic wrap. Place the dough in the refrigerator and chill for at least two hours. You can refrigerate the dough overnight.
Put sugar, flour, salt, and lemon zest in the food processor and pulse a few times to mix.
Add butter and pulse a few times, until the mixture has the consistency of coarse meal.
Empty food processor's bowl onto your work surface
See step 3 above and continue as explained in the following steps (minus the lemon zest, which you have already added).
