Put the flour, sugar, butter, baking powder and zests and mix in a food processor until it becomes crumbly
Next, add the egg and almond extract and continue to gently mix until it becomes doughy
Split into 2 equal parts and put one in the fridge to chill
Press the remaining ball of dough evenly into a greased cake tin to form the base
Then spread your fruit preserves around the center. I used strawberry jam here
Retrieve the chilled ball of dough from the fridge and carefully roll out into a circle the will fit on top of your base. Add a bit of flour here to stop things sticking
Place the rolled dough on top of the base, then trim any leftovers and press the edges to seal
Put in the 200C oven for 15-20 mins or until browned
Allow to fully cool then sprinkle some icing sugar over the top and serve
