Ingredients
Method
Pasta Frolla
- Blend the flour, sugar, baking powder, vanilla powder, if using, salt and lemon zest in a food processor until combined.
- Add the butter, cut in pieces, and vanilla extract, if using, then blend till well combined.
- Add the eggs and blend till the pastry almost forms a ball.
- Remove the pastry from the food processor and use your hands to press everything into a single ball.

- Wrap the pastry in waxed paper and refrigerate for an hour before using.
- Roll the pasta frolla into a 13-inch circle.
- Line a greased 10" deep dish tart pan with a removable bottom with Pasta Frolla going about 1 inch up the sides. Trim the excess and use it to patch the crust if necessary.

Filling and Assembly
- Reserve six amaretti for garnish.
- Crush the remaining amaretti and combine with liqueur, and vanilla extract, if using.

- Soak, occasionally crushing the amaretti further, until thick and batter-like.

- Combine sugar, lemon zest and vanilla powder, if using.

- Combine the egg yolk and the sugar mixture with the amaretti mixture. Mix well.


- Beat the three egg whites and cream of tartar until stiff.

- Fold a spoonful of the egg whites into the amaretti mixture to lighten it.

- Gently fold in the remainder of the whites, in two portions.

- Pour the filling into the tart pan lined with pasta frolla.

- Garnish the top with the reserved whole amaretti.

- Bake at 350°F approximately 30 minutes, until golden brown.
- Cool in pan for about 10 minutes then gently remove the sides of the pan. (I like to do this by setting the pan on a large can then gently jiggling the pan apart.)

- Cool thoroughly on a rack.
- The crostata should be stable enough to slide off the bottom of the tart pan and onto a serving platter.

- Serve with whipped cream, if desired.
