This carbonara swaps out spaghetti for smooth, velvety orzo. It’s up to you how much you want to treat this eggy, peppery comfort like pasta or like risotto, where orzo is used like rice (minus all that stirring). For more of a risotto flavor, you could cook a finely diced shallot, maybe even some celery or celery seed, in the guanciale fat before adding the orzo, then add a splash of white wine. This creamy pantry dish is best eaten right off the heat, but it is odd how, even straight out of the fridge, it still stays glossy somehow, like a dreamy pasta salad.
