This is absolutely delicious. It genuinely very quick to make. Took the filling from Nigella, but did not like the dough she used, so I whipped up a batch a la Delia Smith – the Quick Flaky Pastry (we basically use this as a standard in pastry in our house).
So whip up a batch of that by grating 110g butter (which I pop into the freezer before hand) into 175g of plain flour. Once grated use a metal spoon to stir all the grated butter into the flour, ensuring all little bits are covered. Then add a small amount of cold water and using your hands, but minimising your touching of the dough, bind it together. Adding a little more cold water if needed. Once its a consistent ball of pastry, wrap in cling film and through it in the fridge for at least 30-45mins.
Take the pastry out and roll it to 5mm thick to fill a 25cm flan dish. Press it into the sides and cut off excess pastry, but leaving a little above the rim. Pop the flan dish into the freezer (I had to find space for it, but managed) for 20 minutes, while you make the filling. (Pop it in the fridge if you can’t fit it in a freezer).
To get the filling together; start with a pot or saucepan and let 200g of light brown sugar, 150g unsalted butter and 4 large tablespoons of golden syrup (I only use Lyle’s Golden Syrup, but I believe corn syrup, maple syrup or molasses could do the trick too). Once melted, stir together, although the butter tends to separate, don’t worry about that. Add a teaspoon of vanilla essence, stir again and pull off the heat and leave for ten minutes to cool. Whisk 3 eggs in a bowl and leave ready for after.
Preheat your oven to 180 degrees celcius (or 350 fahrenheit). In the mean time grab the flan dish from the freezer and check that its nice and cold. The freezing protects the shape of the pastry once it gets into the hot oven, so it’s important its crisp and cold.
Grab at least 350g of mixed nuts (they have to be unsalted and ideally with no additives in them). If you want feel free to use only pecans, but its handy to use all the half packs of almonds, hazelnuts, walnuts, pecans etc. I do love an odd brazil nut in here too or a cashew, so be daring. It is delicious after all. Arrange them nicely in the flan dish.
Pop back over to the now slightly cooled filling mix and with your whisk, mix in the beaten eggs, until its a lovely thick caramel-like nom.
Pour gently over the nuts into the pastry case. Pop into the now heated oven for at least 40 minutes or until the the filling has set.
Let it cool a little. Serve with a dash of lightly whipped cream.
