Orzo pasta is a non-negotiable staple in my kitchen. Simply dressed in butter and salt, and maybe a dusting of nutmeg or grated Parmesan, or indeed both, it often serves at my table as a substitute for rice or potatoes, and I regularly use it to cook what in Italian is pasta risottata, a kind of pasta risotto. It makes for wonderful, cosy one-pot dishes, of which this is a pre-eminent example. For US cup measures, use the toggle at the top of the ingredients list.
