I chose to do my crostada with pastry cream and fresh fruit. I used the pastry cream recipe from Annie's Eats. My crust didn't turn out perfectly. I don't know if I overworked it or maybe I didn't bake it long enough. It was still deliciuos, especially with the pastry cream.
pasta frolla
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.
Make a well in the center of the mounded flour and butter mixture and pour the beaten eggs into it (reserve about a teaspoon of the egg mixture for glazing purposes later on – place in the refrigerator, covered, until ready to use).
Add the lemon zest to your flour/butter/egg mixture.
Use a fork to incorporate the liquid into the solid ingredients, and then use your fingertips.
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.
Making pasta frolla with a food processor:
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).
Variation for Version 1 of pasta frolla:
If you want, you can make the pasta frolla using a combination of all-purpose flour and whole-wheat pastry flour.
If you choose to try this variation, use 1 cup [240 ml, 135 g, 4 3/4 oz.] unbleached all-purpose flour and 3/4 cup [180 ml, 100 g, 3.5 oz.] whole-wheat pastry flour.
For the pastry cream:
2 cups half-and-half
1/2 cup sugar
Pinch salt
5 large egg yolks
3 tbsp. cornstarch
4 tbsp. cold unsalted butter, cut into 4 pieces
1 1/2 tsp. vanilla extract
For the topping:
2 large kiwis, peeled, halved lengthwise and sliced
6-9 oz. raspberries
1/2-1 cup blueberries
Apple jelly, for glazing
To make the pastry cream, heat the half-and-half, 6 tablespoons of the sugar, and the salt in a saucepan over medium-high heat until simmering, stirring occasionally to dissolve the sugar. Meanwhile, combine the egg yolks and remaining 2 tablespoons sugar in a medium bowl and whisk until the sugar has begun to dissolve and the mixture is creamy, about 15 seconds. Whisk in the cornstarch until combined and the mixture is pale yellow and thick, about 30 seconds.
When the half-and-half mixture has reached a simmer, slowly add it to the egg yolk mixture to temper, whisking constantly. Return the mixture to the saucepan, scraping the bowl with a rubber spatula. Return the mixture to a simmer over medium heat, whisking constantly, until a few bubbles burst on the surface and the mixture is thickened and glossy, about 30 seconds. Off the heat, whisk in the butter and vanilla. Strain the pastry cream through a fine mesh sieve set over a medium bowl. Press plastic wrap directly on the surface to prevent a skin from forming and refrigerate until cold and set, at least 3 hours and up to 2 days.
To assemble the tart, spread the cold pastry cream evenly over the bottom of the tart shell. Arrange the fruit on top of the pastry cream as desired. Heat the jelly in the microwave for 20-30 seconds, just until slightly melted and easy to stir. Using a pastry brush, paint a light layer of jelly over the fresh fruit. Serve
