Step 1 — Preparing the Pastry Dough
The dough used for Torta della Nonna is called pasta frolla, an Italian sweet shortcrust pastry.
1. Combine Dry Ingredients
In a large bowl mix:
- Flour
- Sugar
- Baking powder
- Salt
- Lemon zest
Stir thoroughly so everything distributes evenly.
2. Add Butter
Add the cold cubed butter.
Using your fingertips or a pastry cutter, rub the butter into the flour mixture until it resembles coarse sand or breadcrumbs.
Important:
Do not overwork the dough. The butter should remain cool.
3. Add Eggs and Vanilla
Add:
- Whole eggs
- Egg yolk
- Vanilla extract
Mix gently until a dough forms.
4. Form the Dough
Turn dough onto a lightly floured surface.
Knead briefly only until smooth.
Do not knead like bread dough because that develops gluten and makes the pastry tough.
5. Chill the Dough
Flatten into two disks:
- One slightly larger for the tart base
- One smaller for the top
Wrap in plastic wrap.
Refrigerate for at least 1 hour.
This step is essential because:
- It relaxes gluten
- Firms the butter
- Prevents shrinking during baking
Step 2 — Preparing the Custard
The custard is the heart of the dessert.
1. Heat the Milk
In a saucepan combine:
- Milk
- Vanilla
- Lemon zest
Heat gently until steaming but not boiling.
Turn off heat and allow flavors to infuse for 5 minutes.
2. Mix Egg Yolks and Sugar
In a bowl whisk:
- Egg yolks
- Sugar
Whisk until pale and creamy.
3. Add Cornstarch
Sift in cornstarch gradually.
Whisk until smooth with no lumps.
4. Temper the Eggs
Slowly pour warm milk into egg mixture while whisking continuously.
This prevents scrambling.
5. Cook the Custard
Return mixture to saucepan.
Cook over medium-low heat.
Whisk continuously.
After several minutes the custard thickens dramatically.
Continue cooking 1–2 more minutes after thickening.
The custard should be thick enough to hold shape.
6. Cool the Custard
Transfer to bowl.
Cover surface directly with plastic wrap to prevent skin formation.
Cool to room temperature.
Then refrigerate 30 minutes.
Step 3 — Preparing the Tart Base
1. Roll Out Larger Dough Disk
Roll dough into a circle approximately:
- 12 inches wide
- 1/4 inch thick
2. Prepare Tart Pan
Lightly butter tart pan.
Place rolled dough into pan.
Press gently into corners.
Trim excess edges.
3. Add Jam Layer
Spread jam evenly across bottom.
Do not make layer too thick.
The jam adds moisture and fruity depth beneath the custard.
Step 4 — Add Custard Filling
Spoon cooled custard over jam.
Spread evenly using spatula.
Smooth top carefully.
Step 5 — Top Layer
Option 1 — Full Pastry Top
Roll second dough disk.
Place over custard.
Seal edges carefully.
Cut small slits for steam.
Option 2 — Lattice Design
Cut strips and create lattice pattern.
Traditional versions often use a full top, but lattice is beautiful and rustic.
Step 6 — Add Pine Nuts
Scatter pine nuts evenly across top.
Press gently so they adhere during baking.
Step 7 — Baking
Bake at:
- 350°F (175°C)
For:
- 45–55 minutes
The tart should become:
- Deep golden
- Slightly firm in center
- Fragrant and buttery
If browning too quickly, tent loosely with foil.
Step 8 — Cooling
This dessert must cool completely before slicing.
Cool:
- 1 hour at room temperature
- Then 2 hours refrigerated
The custard sets fully during this time.
Step 9 — Final Decoration
Dust generously with powdered sugar before serving.
Flavor Notes
This dessert tastes:
- Buttery
- Creamy
- Lightly citrusy
- Vanilla-rich
- Slightly nutty from pine nuts
- Fruity from jam
The contrast between crisp pastry and silky custard is the defining characteristic.
Serving Suggestions
Serve:
- Slightly chilled
- Or at cool room temperature
Excellent with:
- Espresso
- Cappuccino
- Black tea
- Dessert wine
Storage
Refrigerator
Store covered up to 4 days.
Freezer
Freeze slices individually up to 2 months.
Thaw overnight in refrigerator.
Common Mistakes to Avoid
1. Warm Dough
Warm dough becomes sticky and difficult.
Always chill thoroughly.
2. Thin Custard
Custard must be thick before cooling.
Undercooked custard becomes runny after baking.
3. Soggy Bottom
Avoid excessive jam.
Too much moisture softens pastry.
4. Cutting Too Early
Warm custard collapses.
Allow full cooling time.
Variations
Chocolate Version
Add chocolate chips to custard.
Nut Version
Add chopped almonds or pistachios.
Citrus Version
Use orange zest instead of lemon.
Berry Version
Use raspberry jam with fresh berries.

Professional Baker Tips
Use European-Style Butter
Higher fat butter creates richer pastry.
Strain Custard
For ultra-smooth filling, strain through fine sieve before cooling.
Blind Bake for Extra Crispness
Optional:
Bake bottom crust alone for 10 minutes before filling.
This improves texture.
