How to Make It
Take your liquid and put it in a heavy-bottomed pan. Season the liquid with salt, pepper if you like, or any other seasonings that you are feeling up to. A bay leaf doesn’t go amiss, nor does a scrape of nutmeg. But mostly you just need salt. If you have only water, try a bouillon cube or paste.
Bring it to a simmer over medium high heat, then reduce the heat to medium low and pour in your semolina in a steady stream. Whisk the semolina until fully combined with no lumps. Continue to stir while the mixture comes back to a simmer, and watch it thicken to a lovely mashed potato-like consistency in about 2-3 minutes.
Reduce the heat to low and stir in your cheese of choice, whisking until well combined and melted. Check the texture. Want it creamier? Add more liquid. Cheesier? Add more cheese. Taste for seasoning, add any last-minute additions you might want, like lemon zest or chopped fresh herbs, and pile into a bowl. Think it wants a pat of butter melting on top? No one would argue.
