Seafood Risotto

Carnaroli is specified for a reason, not snobbery: it has more of that starchy outer layer relative to its firm core than ordinary rice, and it holds its bite longer while still giving up starch. Arborio works and is far easier to find in a UK supermarket — slightly softer, slightly less forgiving if you overcook it, but it'll get you there. What you can't substitute is any rice bred to stay separate and fluffy — basmati, jasmine, long-grain — because those varieties are selected for the opposite of what you want here. Wrong rice is the single most common reason home risotto turns to porridge or stays stubbornly dry: it was never built to release starch in the first place.

The soffritto — onion, carrot, celery, all finely chopped — isn't flavour for its own sake, it's the base note under the seafood, and it needs to go soft and faintly sweet in oil before the rice ever joins it, not brown and bitter. Watch it, don't time it: the onion loses its raw white-purple sharpness and turns translucent, the carrot gives a little under the spoon instead of staying rigid. Use olive oil here, or any neutral oil with no scent of its own, because you don't want a second competing smell before the sea flavours arrive — butter at this stage would brown and add a dairy note too early; it's saved for the end, where its job is different.

The wine goes in once the rice has had a minute in the hot oil, coated and slightly translucent at the edges — that minute toasts the grain's surface just enough that it won't turn gluey later, a step people skip because it looks like nothing is happening. The wine's alcohol needs to cook off, not sit there raw and sharp; you'll smell the difference, sharp and winey versus rounded and almost disappeared. Any dry white you'd actually drink works — don't reach for "cooking wine," which is usually salted and stale and a false economy for 125ml.

The stock from the prawn shells, scraps and mussel liquor is doing the work that a fish stock cube can't: real depth without the flat saltiness of a cube, built from parts you'd otherwise bin. This is kitchen economics, not romance — a grand kazan-cooked Spanish or Italian seafood rice tradition grew up around using every scrap of an expensive catch, because throwing away flavour when you've paid for the whole animal never made sense to anyone poor. If you genuinely have no shells to spare, a light fish or vegetable stock will carry you, but keep it thin and clean — a heavy, salty commercial stock will fight the delicate shellfish rather than support it.

Mussels and clams are temperamental and worth respecting rather than fearing: any that stay shut after cooking are shut because they were dead before you started, and a dead shellfish doesn't suddenly open from heat — it's sealed, not stubborn. Discard those without a second thought; it's not wastefulness, it's the one food-safety rule in this whole dish that isn't negotiable.

Patience is the actual ingredient that makes this a two-person Sunday dish rather than a Tuesday one — not a long active effort, but a long attended one, ladle by ladle, staying by the pan instead of leaving it. The butter stirred in at the very end, off rough heat, is what pulls all that released starch and stock together into something that moves like a wave when you shake the pan, not a solid clump. Skip that final beat and you've made good seafood rice. Do it, and you've made risotto.
