Pithivier of gratinated potato
This was made with Gruyere cheese, truffle-scented spinach and wild mushrooms. A pithivier is a traditional French dish hailing from the town of Pithivier in the Orléans region. The round, enclosed pie is usually made by baking two disks of puff pastry, with filling stuffed in between. It was on the menu as the vegetarian option at a special meal at the House of the Art Lover, Glasgow. Absolutely delicious!
Originally pithiviers were made with sweet fillings, but are now more commonly savoury. See this website for a good mushroom recipe.
