Creamy Porcini and Spinach Orzo

Dried porcini mushrooms may be a little pricey, but a little goes a long way and the soaking water also becomes a rich, flavoursome stock. Orzo, a small, rice-shaped pasta, makes a good alternative to grains. There’s something very comforting about orzo, which also features in the Mozzarella, Orzo and Basil Oil Salad, so it could be worth cooking up double the quantity.
