Remove roughly 3/4 cup of the mixture and set aside for the topping. Add the egg to the remaining pastry mixture along with the vanilla extract and blitz until the dough begins to clump together.

Mix the jam with a spoon to loosen it. Remove the tart tin from the oven and spread the jam across the base. Use your fingertips to form little clumps of the reserved pastry mix and put these on top of the tart. Pop back in the oven to cook for 15 minutes until the topping is golden brown.
