I always adapt a recipe so I did a layer of sweet potatoes followed by a layer of chopped leeks, garlic, black pepper, thyme leaves, Parmesan and gruyere cheese then poured on some cream. I then repeated this and finished with a layer of sweet potatoes and topped with the cheese mix. Made enough to fill 2 dishes.
