Cooking Rice: Rinsing, Ratios, and Resting

Rinsing is about removing surface starch

You rinse rice to wash off the loose starch clinging to the grains. Left on, it glues them together.

Do not rinse until the water runs clear. Three or four gentle changes is enough; past that you are washing away aroma and surface nutrition as well. Stir through changes of water rather than scrubbing — broken grains turn the pot to porridge.

The water ratio is not a constant

• New-crop rice: already moist, so about 1 : 1 rice to water.
• Older rice: up to 1 : 1.2.
• Brown rice: 1 : 1.5 or more, and soaking is not optional.
• Stickier rice: a little more water and a longer soak.

The rice in your hand matters more than the cups in a recipe. Cook it once and adjust next time — that is the fastest route.

Soaking is for evenness

Thirty minutes closes the moisture gap between the outside and the centre of each grain. Skip it and you get grains that are blown out at the surface and firm in the middle. Twenty minutes in summer, up to an hour in winter.

Soaked rice needs less water in the pot — subtract what it already drank.

Resting is part of the cooking

Off the heat, lid on, for ten minutes. In that time the moisture in the pot redistributes top to bottom and residual heat finishes the centre of the grains. Open it immediately and the top is wet while the bottom has caught.

After ten minutes, cut through it with a paddle from the bottom up to release the steam. Do not press and stir.

For fried rice, the rules invert

Kimchi Bokkeumbap, Egg Fried Rice, Khao Pad and Nasi Goreng fail with freshly cooked rice. It is too wet, so it clumps in the pan and never gets coated.

• Cook it 10% drier than usual.
• Spread it on a wide plate and cool it completely. Overnight in the fridge is best.
• The starch retrograding in the fridge is exactly what makes the grains separate.

When the rice is part of the dish

• Bibimbap: it has to stay loose and separate to mix with the vegetables and gochujang. Slightly less water.
• Gimbap and Onigiri: these need to hold together, so cook slightly wetter. Season with vinegar, salt and sugar (or salted water) and shape it at around body temperature.
• Paella and Risotto: do not rinse. You need the surface starch — risotto builds its creaminess from it, and paella needs grains that drink the stock and stay al dente. Risotto is stirred constantly; paella is never stirred at all.
• Dishes that use rice as cake, like Tteokguk, are a different family again.

Common failures

• Caught on the bottom → heat too high or not enough water. High only until it boils, then the lowest setting.
• Undercooked on top → no resting time, or a loose lid.
• Porridge throughout → too much water, or grains broken while rinsing.
• Everything sticks together → under-rinsed, or not cut through after resting.
