Swiss Walnut Pie (Engadiner Nusstorte or Bündner Nusstorte)

The first time I tasted Engadiner Nusstorte, I was hiking through the Swiss Alps. After hours of breathtaking scenery and crisp mountain air, we stumbled upon a tiny village bakery. The aroma of caramel and toasted nuts wafted out, beckoning us inside. That first bite – the buttery, crumbly crust giving way to the intensely rich, nutty filling – was pure heaven. It was a taste of Switzerland I’ll never forget, and I’ve been striving to recreate that perfect pie ever since.

Recipe Overview

• Prep Time: 1 hour
• Cook Time: 35-40 minutes
• Total Time: 1 hour 40 minutes
• Servings: 12-16
• Yield: 1 pie

Ingredients

For the Crust:

• 350 g flour
• 200 g butter
• 200 g sugar
• 1/4 teaspoon salt
• 1 large egg, beaten

For the Filling:

• 200 g sugar
• 2 tablespoons water
• 250 g walnuts, coarsely chopped
• 150 ml heavy cream
• 3 tablespoons honey
• 1 egg white
• 1 egg yolk
• 2 tablespoons heavy cream

Equipment Needed

• Food processor
• Refrigerator
• Large heavy-based saucepan
• Oven
• 30 cm (approximately 12-inch) pie tin or cake tin
• Cling film (plastic wrap)
• Rolling pin
• Fork
• Wire rack

Instructions

1. Prepare the pastry: In a food processor, combine the flour, butter, sugar, and salt. Pulse until the mixture forms a homogeneous dough. If the dough seems too dry, add 1 or 2 tablespoons of water, one at a time, until it comes together.

2. Chill the dough: Divide the dough into two balls, with one ball roughly twice the size of the other (approximately 2/3 and 1/3 of the total dough). Wrap each ball separately in cling film and refrigerate for at least 30 minutes. This allows the gluten to relax and prevents the crust from shrinking during baking.

3. Make the caramel: In a large, heavy-based saucepan, combine the sugar, water, and honey. Place the saucepan over medium heat and stir gently until the sugar dissolves completely.

4. Caramelize the sugar: Bring the mixture to a boil and let it continue to boil until it transforms into a dark golden color. Stir occasionally to ensure even caramelization and prevent burning. This step requires patience and careful attention, as burnt caramel will impart a bitter taste to the filling.

5. Incorporate the walnuts and cream: Once the caramel reaches a deep golden hue, add the coarsely chopped walnuts and heavy cream to the saucepan. Stir continuously to coat the walnuts evenly in the caramel.

6. Cool the filling: Remove the saucepan from the heat and set the walnut filling aside to cool slightly. It will thicken as it cools, making it easier to spread.

7. Preheat the oven and grease the tin: Preheat your oven to 180°C (350°F). Lightly grease a 30 cm pie tin or cake tin. This helps prevent the pie from sticking and ensures easy removal after baking.

8. Roll out the larger dough ball: On a lightly floured surface, or between two sheets of cling film, roll out the larger dough ball into a circle approximately 34 cm (13.5 inches) in diameter.

9. Line the tin: Carefully transfer the rolled-out dough circle into the prepared tin. Gently press the edges of the pastry against the side of the tin, ensuring that it fits snugly.

10. Fill the pie: Scrape the slightly cooled walnut filling onto the pastry-lined tin. Level the top of the filling as evenly as possible, but avoid applying excessive pressure, which could tear the pastry and cause the filling to leak.

11. Fold the edges: Fold the excess pastry inwards over the filling, creating a neat border.

12. Roll out the smaller dough ball: Roll out the second, smaller dough ball into a circle approximately 29 cm (11.5 inches) in diameter.

13. Top the pie: Moisten the edges of the pastry base in the tin with the egg white. This will act as a glue to seal the top crust. Carefully position the second pastry circle on top of the filling, covering the entire pie.

14. Crimp and seal: Use a fork to crimp and seal the edges of the top and bottom crusts together, creating a decorative pattern and ensuring a tight seal.

15. Egg wash and prick: In a small bowl, mix the reserved egg yolk with 2 tablespoons of heavy cream. Brush this egg wash evenly over the top crust of the pie. Prick the top crust with a fork in several places to allow steam to escape during baking. If desired, you can score a plaid pattern onto the surface with the fork for added visual appeal.

16. Bake the pie: Bake the Swiss Walnut Pie in the preheated oven for 35-40 minutes, or until the crust is golden brown and the filling is bubbling slightly.

17. Cool and serve: Once baked, leave the pie to cool until lukewarm in the tin. Then, carefully loosen the sides of the pie from the tin, release the clip (if using a springform pan), and gently transfer the pie to a wire rack to cool completely. This prevents the bottom crust from becoming soggy.

Expert Tips & Tricks

• Caramel caution: Keep a very close eye on the caramel. The difference between perfect caramel and burnt caramel is a matter of seconds. A candy thermometer can be helpful, aiming for around 340°F (170°C).
• Nut toasting: For an even deeper nutty flavor, lightly toast the walnuts in a dry skillet or in the oven before adding them to the caramel.
• Chilling time: Don’t skip the chilling time for the dough! It’s crucial for a tender, flaky crust.
• Preventing a soggy bottom: Cooling the pie on a wire rack is key to preventing a soggy bottom crust.

Serving & Storage Suggestions

Serve the Swiss Walnut Pie at room temperature, ideally after it has cooled completely. It pairs beautifully with a dollop of whipped cream, a scoop of vanilla ice cream, or a cup of strong coffee or tea. Leftovers can be stored at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, wrap the pie tightly and freeze it for up to 2 months. Thaw overnight in the refrigerator before serving. Reheat gently in a low oven (around 300°F/150°C) if desired.

Variations & Substitutions

• Gluten-free: Use a gluten-free flour blend in place of the all-purpose flour for a gluten-free version.
• Spices: Add a pinch of ground cinnamon, nutmeg, or cardamom to the filling for a warmer, more aromatic flavor.
• Other nuts: Substitute pecans or hazelnuts for the walnuts, or use a mixture of different nuts.
• Crust enhancements: Add lemon or orange zest to the pastry dough for a citrusy twist.
• Dairy-free option: While not a direct substitute for the butter in the crust, a very cold, high-quality vegan butter alternative may work (results can vary). Coconut cream might work in place of the heavy cream in the filling, but be mindful it may alter the flavor.

FAQs (Frequently Asked Questions)

Q: Why is my crust shrinking during baking?
A: This is usually caused by gluten development in the dough. Make sure not to overwork the dough, and allow it to chill properly in the refrigerator before rolling it out.

Q: Can I make the filling ahead of time?
A: Yes, the walnut filling can be made up to 2 days in advance. Store it in an airtight container in the refrigerator. Bring it to room temperature before using.

Q: My caramel is too hard. What did I do wrong?
A: You likely overcooked the caramel. It’s important to remove it from the heat as soon as it reaches a dark golden color.

Q: How can I prevent the bottom crust from getting soggy?
A: Cooling the pie on a wire rack allows air to circulate underneath, preventing the bottom crust from becoming soggy.

Q: Can I freeze the Swiss Walnut Pie?
A: Yes, you can freeze the pie for up to 2 months. Wrap it tightly in plastic wrap and then in foil. Thaw overnight in the refrigerator before serving.
