If you like an extra umami kick, try sprinkling over togarashi (Spicy!) or furikake (Japanese seasonings with seaweed, sesame seeds and other flavoured goodness).
Orzo pasta isn't a must, it just has that nice creamy risotto feel to it!
When adding parmesan and pasta, whisk until silky and creamy, really give it some elbow grease!
If it needs thinning, add some more pasta water until you get the consistency you like.
