Preheat the oven to 200?C (190?C fan), then start by making the pastry. Rub the plain flour into the fat, adding the milk a little at a time until the ingredients come together in a soft dry dough.
Roll out the dough and use to line a loose-bottomed fluted tin ? don?t worry if there are some tears or gaps, just patch it together.
Fry the bacon lardons for a minute or two, and in the meantime, cut the goat cheese into rounds. Arrange the bacon and the cheese in the lined tin, and then dot with In A Pickle Balsamic Onion Relish. Beat the eggs and milk together with a little seasoning, and then pour over the top.
Place in the oven and bake for 20 minutes, or until the filling is risen and just set. Allow to cool for a few minutes before removing from the tin, and sprinkle with fresh parsley to serve.
