To make the pastry, put the plain flour and caster sugar into a bowl and stir it together. Add the butter and use your fingers to rub the butter into the flour mixture until it resembles breadcrumbs. You can also do this in a food processor
Add the egg and mix to form a dough, be careful not to over work it or knead it
Roll out the pastry on a work surface or silicone mat dusted with flour. Line a 9 inch loose bottomed tart tin with the pastry and trim off any overhang
Use a fork to prick the bottom of the pastry then chill it in the fridge for 30 minutes
Pre-heat your oven to 180C Fan/350F/Gas Mark 5
Scrunch up some baking paper and line the pastry, then add baking beans (pie weights) or some dry rice on top. Bake it for 15 minutes
Take the pastry out of the oven and remove the baking beans and paper. Bake the pastry again for 10 minutes on the same temperature, or until golden and it no longer looks raw on the base. Set aside while you make the filling
Reduce the oven temperature to 150C Fan/325F/Gas Mark 3
In a pan on a low heat, melt the butter, golden syrup, light brown sugar and maple syrup together. Once the butter is melted, take it off the heat. Leave to cool for 5-10 minutes
Add the eggs, salt, cornflour and vanilla extract and whisk them in
Stir in the chopped pecans and pour the mixture into the pastry base. I like to put the tart tin onto a baking tray so it's easier to carry to the oven once it's full of the filling
Arrange the other pecans on top, start with the outside circle then work your way to the middle
Bake for 35-40 minutes, until it has a slight wobble to it. Leave to cool fully then refridgerate
Serve with a sprinkle of salt on top, and either ice cream or whipped cream
Store leftovers in the fridge and eat within 4 days
