This traditional Venetian dish, usually made in spring when fresh peas are at their best, is similar to risotto but is slightly soupier and not quite as creamy. Short-grain Arborio rice worked best; it has the necessary starch to thicken the cooking liquid. High-quality Parmesan cheese is key to the dish's savoriness. Simmering the Parmesan rind in the broth is an easy way to add deep savory flavors.
