Ingredients:
- 2 ½ cups all-purpose flour
- 1 cup confectioner's sugar
- ½ teaspoon salt
- 2 sticks cold butter cut into chunks
- 2 cold large egg yolks
- ⅓ cup cold heavy cream
- 1 teaspoon pure vanilla extract
- 1 egg beaten with 1 tablespoon water, for brushing over the crust
Filling:
- 1 cup golden syrup or light molasses or corn syrup
- 2 ¼ cups fresh bread crumbs
- Grated zest and juice of 1 lemon
Steps:
- For the crust, place the flour, confectioner's sugar, and salt in the bowl of a food processor and pulse to combine. Scatter the pieces of butter over the flour mixture.
- Pulse until the mixture resembles coarse yellow meal without any white powdery bits remaining, about 20 pulses.
- Transfer the mixture to a large mixing bowl. Beat the egg yolks with the cream and vanilla and pour them into the flour-butter mixture. Toss with a spatula until the dough clumps together. If the dough is dry, add 1 more tablespoon heavy cream (better too wet than too dry).
- Divide the dough in half, form into disks, wrap in plastic wrap, and chill at least 2 hours or up to 3 days.
- Just before you are ready to roll out the dough, prepare the filling and preheat the oven to 400°F. Warm the golden syrup in a saucepan until it is runny, or microwave it for 1 minute. Combine the golden syrup, bread crumbs, lemon zest, and lemon juice in a mixing bowl and mix well.
- Remove the dough from the refrigerator. On a floured surface, roll out the larger disk to an 11-inch circle.
- Fold it into quarters, brush off the excess flour with a pastry brush after each fold, then unfold it into a 9-inch tart pan, easing the sides gently into the pan and pressing the dough into the fluted edges. Trim the dough even with the rim.
- Roll out the second disk 1/8-inch thick. Cut the dough in long strips for the lattice topping.
- Scrape the filling into the prepared crust and smooth the top with a rubber spatula.
- Lay half the strips of dough over the filling in one direction and the other half in the opposite direction to form a lattice. Trim the overhang. Gently brush the beaten egg over the lattice.
- Bake for 10 minutes, then reduce the temperature to 375F and bake another 25 minutes until the crust is browned and the filling puffs up in the centre.
