Why This Recipe Works
This dish achieves its signature texture through the layering and controlled cooking of the potatoes. The creamy sauce seeps into the sliced potatoes, giving them a luscious mouthfeel. Layering the potatoes with leeks allows each bite to carry a balanced flavor. Cooking at a low temperature helps to meld the flavors beautifully while ensuring the potatoes achieve the right level of tenderness without becoming mushy.
