Rhubarb and Vanilla Pie

How to make a sugar free rhubarb and vanilla pie

Line a baking tray with non-stick baking paper.

Roll the pastry on non-stick baking paper, about ½cm|1/4" thick. Cut out 4 rounds.

Place the rounds on the baking tray and brush with egg yolk.

Mix together the egg yolks, sugar and cornflour.

Heat the cream in a pan and bring almost to a boil.

Slowly strain the hot cream over the egg mixture, stirring.

Pour back into the pan and heat gently, stirring, until the custard is thick enough to coat the back of a spoon. Do not boil.

Pour into a bowl and cover the surface with cling film.

Heat the oven to 200°C (180° fan)  gas 6.

For the filling 

Put the rhubarb, water and sugar in a pan and bring to a boil, stirring.

Simmer gently for 4-5 minutes, until the liquid has reduced and the rhubarb is softened but not mushy. Set aside to cool.

Make a shallow cut in the puff pastry circles 1cm|1/2" in from the edge and all the way around.

Spread the cream filling on each round, leaving the cut borders.

Arrange the rhubarb on the cream.
