Do you really have to stir risotto all the time?

Risotto has a reputation as the dish that keeps you chained to the stove. Part of that is deserved. Part of it is folklore. The useful thing is to know what the stirring actually does, because then you know when it matters and when it doesn't.

What stirring is for

Risotto rice is a starchy, short or medium grain: Arborio, Carnaroli and Vialone Nano are the varieties you will usually see. The classic method adds hot stock a little at a time while you stir, which, as Wikipedia's risotto entry puts it, makes the grains rub against each other and release starch from their outside. That starch thickens the liquid around the rice. That is the creaminess, and there is no cream in it.

So stirring is not superstition. It is how you get starch out of the grain and into the sauce. But you are not whipping egg whites. The rice does not seize up if you look away.

When you can step away

Think of it as attentive, not constant. A good rhythm:

• At the start, when the rice toasts in the fat and the wine goes in, stay close. This takes moments, and rice can catch.
• In the middle, add a ladle of hot stock, stir well for a bit, then let it bubble gently while you do something useful. Come back when the rice looks almost dry and the spoon leaves a clear trail on the base of the pan. Stir, add the next ladle, repeat.
• Towards the end, stay put again. This is when texture is decided.

Two things make stepping away safe: keep the heat at a lively simmer rather than a roar, and keep the stock hot in a pan next to it. Cold stock stalls the cooking, and fierce heat evaporates the liquid before the rice can absorb it.

The cues that it's ready

Forget the clock. Rice varies, pans vary, stoves vary. Taste instead.

• The grain: soft on the outside, with the faintest resistance at the centre when you bite. No chalky core. Similar to al dente pasta, but a touch softer.
• The flow: spoon some onto a plate. It should spread slowly into a gentle wave rather than stand in a heap. Too stiff and it wants another splash of stock; too soupy and it wants another moment on the heat.
• The sound: a thick, lazy blip rather than a busy boil.

Stop a fraction before you think it is perfect. It keeps thickening off the heat.

The finish matters more than the middle

The last step, called the mantecatura, is where the stirring really earns its reputation. Take the pan off the heat and beat in cold butter and grated Parmesan vigorously, which the Wikipedia entry describes as what turns it smooth and creamy. Then cover it and let it rest briefly before serving. If you are going to be lazy anywhere, do not be lazy here.

What about the no-stir oven method?

Oven-baked risotto, where all the stock goes in at once and the pan goes into the oven, makes a perfectly nice rice dish. It is creamier than you would expect, and on a busy night it is a reasonable trade. It is just a different texture: softer, more uniform, less of that loose, glossy flow. We would call it baked rice and enjoy it on its own terms.

Where it goes wrong

• Too much stock at once turns it into boiled rice in soup.
• Stock that tastes of nothing makes risotto that tastes of nothing. Season the stock first.
• Walking away at the end gives you a stiff cake rather than a wave.
