• For the Fontina crust
• 4 thick slices Stale Valdostano rye bread, cut to fit the bowl opening; at least one day old

Method

1. 1
   Set a wide, heavy pot over a medium-low flame. Melt the butter and lard together until the fat is quiet and shimmering. Add the onion, leek, and carrot. Cook, stirring occasionally, until the soffritto is fully softened and the onion is translucent — no colour should develop. The smell is sweet and faintly grassy.
2. 2
   Add the diced turnip, celeriac, parsnip, and potato to the pot. Stir well to coat every piece in the fat. Cook for 2–3 minutes until the raw edge leaves the vegetables — they will begin to smell faintly sweet and earthy rather than sharp.
3. 3
   Pour in the cold water or light broth. Raise the heat and bring to a steady simmer. Cook uncovered for 20 minutes. The liquid should be active but not boiling hard; the root vegetables will begin to yield at their edges.
4. 4
   Add the Savoy cabbage and green beans. Return to a simmer and cook for a further 30 minutes. All vegetables must be completely tender — press a piece of turnip or parsnip against the side of the pot with a spoon; it should offer no resistance. Season generously with salt and black pepper. Taste and adjust.
5. 5
   Heat the grill to its highest setting. Ladle the soup into four oven-safe serving bowls — terracotta is ideal. If using the optional butter, place a small knob in each bowl now. Lay one thick slice of stale rye bread flat on the surface of the soup in each bowl; it must rest on the liquid, not sink. Arrange 2–3 slices of Fontina d'Aosta DOP over the bread, covering it entirely to the rim of the bowl. This step is where the dish lives or dies: the bread must be genuinely stale so it holds its structure beneath the melting cheese, and the Fontina must be authentic DOP — its particular fat content and alpine character produce the specific melt, the pull of the strings, and the mountain-herb note that defines the dish; no substitute replicates this.
6. 6
   Place the bowls under the hot grill for 3–4 minutes. Watch without stepping away: the Fontina is ready when it has melted completely, bubbles actively across its entire surface, and the edges have taken on patches of pale gold. Remove immediately and serve in the bowls — the cheese will continue to cook from residual heat.
