175g/6oz plain flour
75g/2½oz chilled butter
2-3 tbsp cold water
1 tbsp raspberry jam
125g/4½oz butter
125g/4½oz caster sugar
125g/4½oz ground almonds
1 free-range egg, beaten
½ tsp almond extract
50g/1¾oz flaked almonds
1- To make the pastry, measure the flour into a bowl and rub in the butter with your fingertips until the mixture resembles fine breadcrumbs.
2- Add the water, mixing to form a soft dough.
3- Roll out the dough on a lightly floured work surface and use to line a 20cm/8in flan tin.
4- Leave in the fridge to chill for 30 minutes.
5- Preheat the oven to 200C/400F/Gas 6 (180C fan).
6- Line the pastry case with foil and fill with baking beans.
7- Bake blind for about 15 minutes, then remove the beans and foil and cook for a further five minutes to dry out the base.
8- For the filing, spread the base of the flan generously with raspberry jam.
9- Melt the butter in a pan, take off the heat and then stir in the sugar.
10- Add ground almonds, egg and almond extract.
11- Pour into the flan tin and sprinkle over the flaked almonds.
12- Bake for about 35 minutes.
13- If the almonds seem to be browning too quickly, cover the tart loosely with foil to prevent them burning.
