For the pastry, blitz everything bar the water in a food processor then dribble in enough cold water to bring the dough together, pulsing the machine as you go.
-
Or make traditionally by rubbing in the butter to the flour and sugar then stir in enough egg and water to bring together.
-
Either way, wrap in cling and refrigerate 30 mins.
-
Roll out to a 11 inch circle between two sheets of cling, lightly flour the dough first if it's a little sticky.
-
Peel off one layer of cling then line a 9 inch spring form pan with the dough (I lined my tin with parchment but feel free to butter and flour it lightly instead)- peel off the second layer of cling. Spread the jam on the pastry base then return to the fridge as prepare the filling.
-
Whisk the eggs and white, sugar and zest until much increased in volume and pale in colour.
-
Sift over a third of the flour, salt and baking powder then add the butter with the next third of the flour - fold in lightly.
-
Fold in the final third of the flour then pour gently from a low height onto the jam covered pastry.
-
Bake in an oven at 180˚C until risen, golden and springs back to your touch - between 35-45 minutes depending on your oven.
-
Cool for 5mins then unclip the sides of the tin.
-
Cool until more or less room temp on a rack then remove off the base too.

Delightful served with Greek yogurt or Creme Fraiche whilst still a touch warm, mmmmm :)
