Wrap in cling film and refrigerate for at least 30 minutes.
Roll chilled dough to 2mm thickness on a lightly floured surface and drape dough over tart ring on a lined baking tray. Tuck in the edges, cutting excess on the edges, prick the center a few times and blind bake for 15 minutes. After blind baking, bake for a further 15 minutes or until golden.
Once baked, allow to cool then use extra egg yolk to thinly coat the tart and bake for a further 5 minutes in the oven.
Remove from the oven and let it completely cool. Then coat the inside of the tart with melted white chocolate, set aside until needed.
