Instructions
Read through once, then cook at your own pace with the illustrated guide above.
- 1
In a large bowl, combine 2 cups of all-purpose flour, 1/2 cup softened unsalted butter, 1/4 cup granulated sugar, and 1/4 teaspoon salt.
- 2
Add 1 large egg to the mixture and knead until a dough forms. Wrap in plastic wrap and chill in the fridge for about 30 minutes.
- 3
Meanwhile, in a saucepan, combine 4 cups of chopped walnuts, 1 cup of heavy cream, and 1 cup of brown sugar over medium heat. Stir occasionally until the sugar dissolves and the mixture thickens, about 10 minutes.
- 4
Remove from the heat and stir in the honey and water; cool until thick but still spreadable.
- 5
Preheat your oven to 350°F (175°C).
- 6
Reserve one-third of the chilled dough for the lid. Roll the rest and line the base and sides of a 9-inch tart pan.
- 7
Spread the cooled walnut caramel in the shell, leaving a clean rim.
- 8
Roll the reserved dough into a full lid, place it over the filling and seal it firmly to the rim so the walnuts are completely enclosed; prick the top lightly.
- 9
Bake for 35-40 minutes until evenly golden, then cool completely in the pan before slicing.
