To make the pastry dough, add flour in a large bowl, add butter and start rubbing using your fingers. Add the sugar and the orange rind, then add the egg yolk and mix together. Start adding the ice-cold water a table spoon at a time until it forms a homogenous dough.
Knead the dough briefly until smooth. Wrap in a cling film and refrigerate for about 30 minutes.
Preheat the oven to 200C and butter a 20cm tart tin.
Roll out the dough on a lightly floured surface and line the prepared tart tin with parchment paper and add baking beans( I used rice, you can use any grain as long as it has weight and blind bake for 15 minutes. Blind baking means baking the pastry with any filling.
After 15 minutes remove the rice/beans and return to the oven for 5-10 minutes to cook the base of the pastry.
To make the custard filling, put the whole eggs, egg yolks and sugar in a bowl and whisk.
Place cream and milk in saucepan and bring to a boil under low heat.
Once boiled add the hot milk to the egg mixture as you whisk constantly then strain into the pastry case
Lower the oven temperature to 150 C and place the tart in the oven. Bake for 45 minutes, until the center is lightly set.
Remove from the oven and leave at room temperature until cold.
Serve with strawberries and enjoy.
