Crust: Stir together the flour and sugar in a large bowl. Work in butter until the mixture becomes crumbly. Stir in water a tablespoon at a time, just until the dough comes together and is no longer dry. Form into a ball and wrap with plastic then refrigerate 30 minutes.
Preheat oven to 180 degrees C.
Roll out the dough on a floured surface and line a 25cm pie tin. Trim excess from the edges of the tin. Pierce the bottom of the dough several times with a fork then set aside.
Filling: Whisk the eggs in a large bowl until soft peaks form. Gradually whisk in the sugar, flour and half of the mixed spice. Continue to whisk until firm peaks form.
Beat in honey, then fold in ricotta cheese until evenly combined. Pour the filling into the prepared crust and smooth the top with a moistened knife.
To Cook: Bake in preheated oven until the centre is set and the top is dark golden brown, 50 to 60 minutes. Once cooked, remove from oven and sprinkle with remaining mixed spice.
