Step 1

In a medium sauce pan, combine the sugar and golden syrup over medium heat. Stir until the sugar dissolves and the mixture is bubbling. Add the cranberries and lemon zest and turn over several times to coat evenly with the sugar mixture. Remove the pan from the heat and set aside to cool to room temperature.

Step 2

Prepare the dough: If using a food processor, combine the dry ingredients in the processor bowl and pulse to combine. Drop in the butter pieces and pulse several times until the consistency of oatmeal. If preparing by hand, combine the dry ingredients in a large mixing bowl. Add the butter pieces and cut in with two knives or a pastry blender until the mixture is the consistency of oatmeal.

Step 3

Continue preparing the dough by adding the water one tablespoon at a time until the dough just barely comes together in a ball. Turn the dough out onto the counter and gather up and shape into a disk. Wrap tightly in plastic wrap. Chill in the refrigerator for at least 30 minutes.

Step 4

Unwrap the dough and place on a lightly floured surface. Roll out to a rough 9-inch circle. Carefully transfer to a 9-inch tart pan with removable bottom. Press the dough into the pan and then form a lip around the edge by turning the pan while gently pinching the lip between your left thumb on the outside and right thumb and forefinger on the inside. Chill the prepared pan for 10-15 minutes.

Step 5

Preheat the oven to 375°F.

Step 6

When ready to bake, remove the prepared pan from the refrigerator and prick the bottom a few times with the tines of a fork. Line the bottom of the tart shell with pie weights or a layer of parchment paper and uncooked beans. Bake for 10 minutes or until crust begins to show some drying and browning.

Step 7

Remove the tart shell from the oven and pour the cool cranberry mixture into the shell, spreading it out from the middle so as not to drip on the lip of the crust. Drizzle any remaining sugar mixture from the pan throughout the shell, again avoiding the lip of the tart.

Step 8

Bake for another 30 minutes, or until crust deepens in color and the filling is bubbling. Cool on a wire rack. Carefully remove the outer ring, and serve while still warm, or at room temperature. Top with a scoop of ice cream, or a dollop of cream.
