Roman-Style Semolina Gnocchi with Parmesan

Milk and semolina are the whole skeleton of this dish — everything else, including the cheese, is seasoning on top of a technique. Semolina here isn't standing in for flour; it's chosen because its coarser, harder starch granules swell slowly and hold their shape once set, which is exactly why this can be sliced into firm discs rather than collapsing like a cooked cornflour sauce would. If you can't find semolina, fine polenta (cornmeal) behaves close enough — same slow-swell logic — though the flavour tilts sweeter and the texture a touch grittier. Ordinary flour won't do this job; it gelatinises differently and you'll get paste, not porridge that sets firm on cooling.

Butter goes in twice, for two different jobs. Half goes into the milk at the start to carry fat through the whole mixture — fat coats the starch granules a little and keeps the final texture from tasting like plain hot milk thickened with dust, which is what unbuttered semolina porridge tastes like. The second half goes on top before baking, where its job is purely to help the cheese melt and brown rather than just dry out under the grill's heat. Any neutral fat with no smell of its own could stand in for the first addition — a flavourless vegetable oil, say — but you'd lose the richness that makes this a dish and not a cereal. For the topping, though, butter's the only sensible choice: its milk solids are what brown and give you that nutty crust smell under the grill.

The egg yolks are a binder and an enrichener, not a leavening agent — there's no rise to speak of here, so don't expect puffiness. They firm the mixture slightly as it cools and add colour and a silkier mouthfeel. Beat them lightly before adding and stir them in off the direct heat or just as it's coming off, because a hot pan plus raw yolk straight in risks scrambling at the edges — small flecks of cooked egg in your smooth porridge, which nobody wants to find.

Parmesan and Pecorino do different work despite both being hard sheep-or-cow cheeses grated fine. Parmesan, worked into the hot mixture, melts in and seasons it from within — savoury depth, less saltiness. Pecorino Romano, scattered on top before baking, is sharper and saltier and is there to crust and bite through on the surface, giving contrast rather than blending in. If you've only got one cheese in the fridge, use it for both jobs rather than skipping either step — the dish survives on one hard cheese, it just loses a layer of contrast. A vegetarian hard cheese without animal rennet works exactly the same way if that matters to you.

Nutmeg is doing real work, not decoration — milk-based sauces taste flat and slightly cloying without it; a few scrapes cut that cloying edge the same way it does in a béchamel. Sage leaves tucked in before baking crisp slightly in the butter and give you a herb note that cuts the richness of all that cheese and milk — if you haven't got sage, a few thyme leaves do something similar, though the character shifts.

Patience here isn't about hovering — it's about the 30 minutes you let the cylinder cool and set before slicing. Cut it warm and soft and the slices smear instead of holding a clean edge; the slice has to firm up as the starch sets properly on cooling, the same physics that makes a cooled cake slice cleaner than a warm one. Rush that step and you'll be baking a shapeless heap instead of neat overlapping coins — it'll still taste fine, it just won't look like the dish it's meant to be.
