Why does my risotto go stodgy?

The four causes of a solid risotto — wrong rice, cold stock, too much liquid at once and serving it late — and how to loosen one that has already set.

Short answer

Stodgy risotto is usually the rice sitting too long after cooking, or stock added too fast and too cold. Risotto should be loose enough to spread slowly when the pan is tilted, and it must be eaten within a few minutes of that point.

Risotto is a suspension of starch in liquid, and a suspension only holds while it is moving and warm. Almost every stodgy risotto is one that stopped being either.

What you'll need

A wide, heavy-based pan rather than a deep saucepan
Stock kept at a simmer in a second pan
Risotto rice — arborio, carnaroli or vialone nano

Step by step

Check you are using risotto rice.Arborio, carnaroli or vialone nano. Long-grain and basmati release the wrong starch and simply will not do this. Carnaroli is the most forgiving of the three if you tend to overcook it.
Keep the stock simmering in a separate pan.Cold stock drops the pan temperature every time you add it, which stops the grains releasing starch evenly and stalls the cooking. This is the most common single cause.
Toast the rice before any liquid.Two minutes in the fat until the grains look translucent at the edges with a white centre. It firms the outside of the grain so it holds its shape rather than collapsing into paste.
Add the stock a ladleful at a time.Enough to just cover, then wait until it has almost gone before the next. Flooding the pan boils the rice rather than coaxing starch out of it, and boiled risotto rice goes stodgy.
Keep it at a lively simmer, not a boil.You want steady bubbling around the edge. A hard boil breaks the grains up; too low and the starch never releases.
Stir regularly rather than constantly.Every thirty seconds or so is enough. Continuous vigorous stirring beats the grains apart and produces exactly the gluey texture you are trying to avoid.
Start tasting at 16 minutes.Most risotto rice is done between 18 and 22 minutes, but the only reliable test is biting a grain. It should be tender with the faintest firmness at the centre.
Stop while it still looks too loose.It thickens noticeably in the two minutes after the heat goes off. A risotto that looks correct in the pan will be solid on the plate.
Beat in cold butter and cheese off the heat.The mantecatura. Cold butter and grated parmesan, stirred in hard with the pan off the heat, is what makes it creamy. Adding them while it is still cooking does not achieve the same thing.
Rest it for two minutes, covered.It lets the texture even out. Longer than that and it starts to set.
Check the consistency before serving.Tilt the pan — it should spread slowly like thick lava, not hold its shape and not run. If it holds, loosen it with hot stock now rather than at the table.
Serve it immediately.Warm bowls, and everyone already sitting down. Risotto held for ten minutes is a different and worse dish, and no amount of technique earlier compensates for that.
Use a wide pan next time.A deep narrow saucepan gives a thick layer of rice that cannot evaporate properly, so it steams and turns claggy. Wide and shallow is the shape that works.

Tips

It should spread slowly when you tilt the pan. If it holds its shape, it is already too thick.
Hot stock, one ladle at a time. Cold stock added in bulk is the commonest cause of a solid risotto.
Stop cooking while it still looks slightly too loose — it thickens in the time it takes to reach the table.

Common mistakes

Making risotto in advance and reheating it — The starch sets as it cools and cannot be fully brought back. If you must hold it, undercook by a few minutes, spread it thin to cool fast, and finish it with hot stock later.
Stirring constantly and vigorously — It breaks the grains and turns the dish to paste. Regular gentle stirring releases the starch without destroying the rice.

If it doesn't work

Thick and solid on the plate

Cause: Cooked too far, or held too long before serving — Fix: Stir in hot stock a splash at a time until it loosens. It will not be perfect but it will be edible.

Gluey and pasty

Cause: Over-stirred, or wrong rice — Fix: Nothing to be done now. Next time stir less, and check you are using arborio or carnaroli.

Grains hard in the middle, dish already loose

Cause: Heat too low, or stock added too fast — Fix: Raise the heat to a lively simmer and continue adding stock in small amounts until the grains soften.

Watery and separated

Cause: Too much stock at the end, or no mantecatura — Fix: Simmer briefly to reduce, then beat in cold butter and parmesan off the heat.

Bottom catching and tasting scorched

Cause: Pan too thin, or heat too high with too little liquid — Fix: Move to a heavy-based pan and keep enough stock in it that the base is never dry.

Questions people ask

Does risotto really need constant stirring?

No. That is the most persistent myth about it. Stirring every thirty seconds releases plenty of starch, and constant vigorous stirring actively damages the grains.

Can I use ordinary long-grain rice?

Not for risotto. Long-grain varieties have the wrong starch composition and will not go creamy — you get separate grains in a thin liquid. Arborio, carnaroli or vialone nano only.

Can I make risotto ahead for guests?

Partially. Cook it about two-thirds of the way, spread it on a tray to cool quickly, then finish with hot stock just before serving. Fully cooking it in advance does not work.

Why is cream not in the recipe?

Because the creaminess comes from the rice starch and the butter and cheese beaten in at the end. Cream masks the texture rather than creating it.
