25 minutes before cooking: place the 50 g dried porcini in a heatproof bowl. Pour exactly 500 ml freshly boiled water over them. Cover with a plate and set timer for exactly 20 minutes.

While porcini soak, slice fresh mushrooms 5 mm thick. Dice shallot to 2 mm (brunoise). Keep stock gently simmering in a separate pot.

After 20 minutes, lift porcini out with a fork (do not pour, grit stays at bottom). Squeeze gently, chop finely, set aside. Line a fine sieve with a coffee filter or paper towel, slowly strain the soaking liquid into a measuring jug. You should have ≈450–480 ml dark, fragrant porcini stock. Top up with simmering stock to reach 1.4 L total hot liquid.

Heat your widest sauté pan (14–16 inch) over medium-high. Add 40 g butter + 1 tbsp olive oil. When foaming, add fresh mushrooms in one layer. Cook undisturbed 6 minutes until deep golden underneath. Toss, cook another 4–5 minutes. Season lightly, remove to a plate.

In the same pan (do not wipe!), add remaining 60 g butter + diced shallot. Cook 3 minutes until translucent. Add orzo + chopped rehydrated porcini. Toast 4 full minutes, stirring constantly, until orzo turns golden-brown and smells nutty.

Add garlic + thyme. Cook 30 seconds. Pour in white wine, scrape every brown bit, reduce by half (≈2 minutes).

Reduce heat to medium. Begin the risotto dance: add 1 ladle (≈125 ml) hot porcini/stock liquid. Stir until almost absorbed. Repeat, stirring almost constantly but gently, for 18–22 minutes. After 15 minutes, taste an orzo grain, it should be al dente with a tiny white core.

When the last ladle is almost absorbed, return browned fresh mushrooms to the pan with their juices. Stir. Taste and adjust salt (remember cheese is coming).

Remove pan from heat completely. Add mascarpone in dollops + all microplaned cheeses in 4 stages while beating vigorously with a wooden spoon (mantecatura). Add final 2–3 tbsp cold butter cubes. The sauce will turn from loose to impossibly creamy and glossy. If too thick, add a splash more hot stock.

Cover and rest exactly 5 minutes off heat. Uncover, stir once, spoon into warmed wide bowls, finish with a few drops white truffle oil, extra Parmesan snow, cracked pepper, and chives. Serve immediately with chilled white Burgundy and absolute silence for the first three bites.
