Though you may associate bocconcini with the tiny mozzarella balls sold at Italian markets and cheese shops, the word simply means "little bites" (the veal in this stew is cut into bite-size pieces). When purchasing dried porcini, look for packages containing large, flat, recognizable slices of the mushroom.
