Should You Wash Rice Before Cooking?
It is generally recommended to wash rice before cooking it, especially if you are using white rice. Rice often contains small amounts of dust, dirt, and other impurities that can be removed by washing it. Washing the rice also helps to remove some of the excess starch that can make the cooked rice sticky and clumpy.
For different kinds of rice, and depending on what you are making, there is some variation as to how much washing is necessary, and how much it is beneficial. The main reason to wash is to get rid of the surface starch on your rice grains, which makes them sticky when you bake them. The old saying is to wash rice until the water runs clear, or until you can clearly see the individual rice grains through cloudy water. It is recommended to thoroughly rinse your rice in running water right after you cook it.
After you rinse your sushi rice thoroughly, put it aside to dry for several minutes before you cook. Basically, regardless if you just rinsed your rice, or you soaked it with lots of water, you always want to thoroughly drain it before adding in the water to cook it. Japanese Short Grain Rice, for instance, after being rinsed and fully drained for 10-15 minutes, is best left soaking for 30 minutes in its actual cooking water before turning on the heat.
| Steps | Time |
| Rinse and drain | For 10-15 minutes |
| Soaking | For 30 minutes |
To clarify, even if you wash short-grain rice, such as sushi rice, the cooked grains will still bond together (they are supposed to). For some varieties of rice, washing your rice is beneficial, and will impact the end texture of the short-grain varieties, such as sushi rice.
Rinsing or washing the rice removes this extra starch, which results in the grains being more separated during cooking. When you wash white rice, that surface starch is sort of separated out from the rice, staying with the water.

You have probably noticed that there is this white, powdery layer on top of your rice, which is easy to rinse away during rinsing, so before you begin cooking your white rice, there is no need to rinse it. Rinsing helps to remove all the impurities in rice, and it keeps your rice from sticking together while you are cooking. Rinsing your rice is easiest done with a strainer or strainer, but you can also wash your rice in the pan that you will then be cooking it in.
Also, if you allow your rice to sit in a little bit of clear water for a couple of minutes, it will get rid of any surface starch, preventing it from sticking together or becoming sticky (via The Kitchn). If these grains of rice are not washed prior to cooking, that remaining starch will be gelatinized in hot cooking water, and make cooked grains of rice sticky. Soaking wets these grains of rice, and then the amylose and amylopectin within the starch grains soak up the water and expand.
Soaking helps the rice have a better, uniform texture, rather than drying out with an unevenly steamy, flaky interior. When white rice is milled, the outer shells and bran layers are removed in order to create translucent grains, but that removes certain vitamins and nutrients as well. Most white rice produced in the United States is carefully washed, and then enriched with vitamins and other nutrients, which show up in the form of dusty layers on the individual grains. White rice typically needs a good wash before cooking, in order to remove its starchy coat — failing to wash it results in rice that is smellier and that spoils more quickly.
That said, white rice is usually judged by the degree to which its grains are separated, so if light, fluffy rice is what you are after, washing is crucial. To make sure you get a light, fluffy rice, we always remove surface starch by washing the raw grains under cool running tap water in a fine-mesh strainer prior to cooking.
Ed Kernan says that generally, after washing your grains, you can expect to get light, fluffy rice dishes. When it comes to longer-grain varieties such as basmati and jasmine, Kernan says it depends entirely on the recipe if the rice should be washed. When you rinse a long-grain rice, such as basmati or jasmine, what you really get is separate, individual grains. In cases like biryanis and pilafs/pulaos, which use long-grain rice such as basmati – and are judged for quality based on the degree to which cooked rice grains are separated – washing away any nastiness becomes really important.
When it comes to rice dishes that require grains to stick together more, such as rice puddings or risottos made with arborio rice, the recommendations are divided. When it comes to brown rice, messages are equally split on whether you need to wash it, and how that may impact the texture.
Some people swear that solid rinses are what gives cooked rice a puffy texture (not sure what goopy rice fits into that). Washing is a vigorous process that involves repeated rinses, but the focus is not on purity, but on making sure that the rice tastes as great as possible.
Even after being processed, the rice still has a sticky covering called the hawai nutka (literally, skin nut) which is the part that needs to be washed away. When you mistakenly prepare the rice with starchy residue left intact, it will give you rice that has a somewhat slimy texture, as well as developing sticky clumps, which is not ideal. Unwrapping and stirring the rice after it has started cooking breaks the grains, which results in a gummy rice and is not a great texture.
I prefer this method for washing rice as it gives a better visual finish point for measuring when to stop (and the mesh keeps any grains from ending up in your kitchen sink). Scientists studying the effects of washing on rice texture have said that washing basmati rice three to five times, and medium-grain rice two to three times, should work.
It may be a good idea to wash brown rice and other types of whole-grain rice to get rid of the mud, insects, and any other undesirable materials. While the starch powder may be helpful in thickening the broth, the rice still needs to be washed prior to cooking in order to remove any possible soil, chemicals, and bugs. In the case of rice, wash means to put the grains into water until the water runs clear, and this is a task that requires a bit more than just washing.

The enrichment of rice grains is done after grains are dehulled and polished, and water-washing rice removes those nutrients. By washing this kind of rice, an over-gelatinization process would take place, which means that a risotto would be especially starchy, and that ingredients flavors would not penetrate into the rice.
What happens if you dont wash rice?
The rice grains are covered in starch dust due to the friction between the dry grains. This leftover starch will gelatinize in the hot cooking water if the grains aren’t cleaned before cooking, causing the cooked grains of rice to adhere to one another. True, harmful side effects of not washing your rice include contaminants like cadmium, lead, and water-soluble arsenic.
Can you get sick from unwashed rice?
Bacillus cereus, a microbe that can result in food poisoning, can be found in uncooked rice’s spores. Even after the rice is cooked, the bacteria can still live, and the longer the rice is kept out at room temperature, the more likely it is that the bacteria will grow and perhaps produce toxins.
What is fried rice syndrome?
The bacterium often just causes diarrhoea and vomiting, but in rare instances, it can harm the liver and lead it to fail. Since rice is occasionally fried and allowed to cool at room temperature for a few hours, the bacterium is most known for producing a condition known as “Fried Rice Syndrome,” which is a kind of food poisoning.
