Ingredients
Method
Preparing the pie crust
- Combine the cold butter with the flour and salt in a food processor until the mixture resembles coarse meal.
- Mix a tablespoon of white vinegar into a third of a cup of ice-cold water, then pour this over the flour mixture and carefully toss with a fork until a dough begins to come together.
- Divide the dough into two balls, flatten them into six-inch rounds, wrap in plastic wrap, and refrigerate for at least 20 minutes.
Rolling out the dough
- Flour your surface and roll out one dough into a 12 to 14-inch round.
- Place the rolled dough in the bottom of a 9.5-inch pie plate and chill in the freezer for 10-15 minutes.
Making the filling
- Combine maple syrup, brown sugar, butter, and a pinch of salt in a saucepan over medium-low heat and bring to a boil, then simmer for about five minutes.
- Remove from heat and stir in the whipping cream and vanilla extract; allow it to cool to room temperature for about an hour.
- Whisk in the eggs and flour until smooth, then fold in the walnuts before pouring the filling into the chilled pie shell.
Baking
- Preheat the oven to 375°F (190°C) and place the pie on the lower rack of the oven. Bake for 15 minutes.
- Reduce the heat to 350°F (175°C) and continue baking for an additional 35-45 minutes until golden brown.
Cooling
- Allow the pie to cool to room temperature before refrigerating until serving.
Notes
For a richer flavor, consider toasting the walnuts lightly before adding them to the filling. This pie is best served warm or chilled, possibly topped with whipped cream or ice cream.
