The best mushroom risotto I have ever eaten was in a hotel kitchen in Rotterdam. Pale, glossy, faintly perfumed with truffle. I have been trying to cook that bowl ever since.
A take on a classic risotto in the spirit of Theo Randall and Marco Pierre White. Hot stock, patient stirring, restraint with the truffle.
The Rotterdam bowl, redone at home. Rocket lifts the finish without crowding the mushroom.
The non-negotiable bit is the stirring. The starch in arborio rice only releases when the grain is moving against itself in hot stock. Cold stock and a low stir gives you a pan of rice in liquid. Hot stock and a constant stir gives you risotto.
Sourcing the mushrooms
The shiitake and wild specialties are the flavour. The dried porcini are the depth; soak them in chicken stock for 20 minutes and the soaking liquor becomes part of the cook. If you cannot find the specialty mushrooms, chestnut or portobello work; the dish loses a touch of the perfume but holds the structure.
Mise en place. The dried porcini are at the back; the truffle stays in its wrap until the very end. Texture you can feel through the lid. Keep the chop coarse; the mushrooms shrink hard in the pan.
The recipe
Step shots
Truffle and parsley, ready for the last five minutes. Drive the water out of the fresh mushrooms before the porcini join them. One ladle at a time. Stir, wait, stir again. Topped with parmesan, rocket, and a final shaving of truffle. The rocket is more than garnish; it lifts the truffle off the plate. One very delicious delicate mushroom risotto. The Rotterdam version is still better, but only by a shaving.
Inspiration worth watching
I leaned on two recipes in particular while working this one out.
