Smoked Salmon and Courgette Tart

This is a beautiful tart with a rich savoury custard, salmon and caramelised onion in a shortcrust pastry. It makes a fantastic packed lunch, picnic centrepiece or dish to impress friends and family at the weekend. Don’t be nervous around the pastry: it can sense your fear. Just relax and remember that the filling is the star of this show.
