The ingredient list provides raw quantities, but dense white potatoes like those from Val di Chiana carry varying water weights depending on storage age. Slice tubers into uniform 1-centimeter cubes to ensure equal heat penetration during the initial twenty-minute sweat. Allowing porcini mushrooms to release their liquid entirely before adding water concentrates umami compounds directly in the olive oil base.
Multiplying this recipe requires adjusting pot dimensions rather than just ingredient amounts. Standard domestic pots crowd quickly, trapping steam and preventing the crucial reduction phase where mushroom moisture evaporates. Maintain a wide base surface area when doubling the batch so the 750 milliliters of water reduces properly over low heat without turning the potatoes into a watery mash.
Over-processing the chestnuts ruins the structural balance between chunky root vegetables and soft fungi. Crumble steamed chestnuts by hand rather than puréeing them mechanically, reserving whole fragments for the final garnish. Finish the dish with freshly cracked black pepper and a final drizzle of cold-pressed oil only after removing the pot from the burner.
