Neither a cottage, nor a shepherd’s pie, but a pork and leek one. Its exactly the same format as any other potato pie, but outdoes its competitors by a long mile. You can use minced pork, or if you feeling idiotic like me you can painstakingly hand cut pork into smaller pieces. Fry it of in a hot pan to remove the fat, and add some garlic, a chopped onion and diced leeks. Allow this to cook off before adding a small amount of stock to thicken up into a sauce. Meanwhile you can add some chopped potatoes to a pan of boiling salty water until al dente. Drain and mash, with a proper mashing utensil, not a fork. Add a tablespoon of wholegrain mustard and mix well. Pour the leek and pork mixture into the bottom of an oven proof dish. Cover with the potato and use the back of a fork to create ridges and grate some cheddar before placing under the grill to crisp up.
