Washing or Soaking Rice – Does That Make Sense?

Before preparing it, you should wash and soak rice. We explain why and what you should pay attention to.

At first glance, it is actually quite easy to cook rice. If we take a closer look at the topic, it becomes apparent that there are quite a few things to consider when preparing rice. It’s not just about the consistency and taste of the cooked rice, but also about the health aspects. Find out here why you should definitely wash and soak rice.

Washing and soaking rice: That’s why it’s so important

Some people cook rice directly without washing it first. Others swear by washing the grains thoroughly beforehand. Very few, however, remember to soak the rice beforehand. These are important steps, because with the right preparation you can reduce the arsenic contained in rice.

Background: In recent years, various studies and investigations have repeatedly found arsenic residues in rice. Arsenic is a semi-metal that occurs naturally. This element is classified as “carcinogenic to humans” according to the International Agency for Research on Cancer (IARC). This is why there have been maximum levels for arsenic residues in rice and rice products in the EU since 2016.
Arsenic can also be found in other foods such as bread or cow’s milk, but rice is particularly contaminated. This is because the rice fields are flooded during cultivation and the arsenic is released from the soil. Arsenic was found in all six products examined in a WDR random sample study. More information on this topic: Arsenic in food.
Due to the arsenic residues found, the Federal Office for Risk Assessment (BfR) advises against consuming rice too frequently and in too large quantities. Instead, you should replace rice and rice products with other grains and foods – especially for babies and children. Incidentally, brown rice and parboiled rice are particularly affected, since the arsenic is mainly deposited in the outer layers of the grain. However, these types of rice also contain more valuable nutrients than white, polished rice.
But you don’t have to do without rice completely, because the method of preparation plays a major role and can significantly reduce the arsenic content in rice. It is important to wash the rice before preparation – and preferably even soak it.

Soaking, washing and cooking rice: arsenic content

There are two popular methods of cooking rice: the swelling method and the water method. (More info on the two methods: Cook rice)

Culinary connoisseurs argue about which method gives the rice the best consistency and tastes best. Scientists, on the other hand, want to find the preparation method that can remove the most arsenic from the rice.

A study from 2015 took on this task and tested various methods. The results for this:

Thorough washing can leach some arsenic from the rice.
The arsenic contained can be reduced even more by soaking the rice for several hours beforehand.
The rice-water ratio when cooking is also crucial. With the swelling method (water 2:1 rice) almost all of the arsenic remains. For the test, the researchers cooked the rice in the ratios 3:1, 6:1 and 12:1. The more water you use, the more arsenic you can end up rinsing out with the cooking water.
The researchers achieved the best result by soaking the rice overnight, then washing it and then boiling it in water at a ratio of 12:1. With this method, over 80 percent of the arsenic could be reduced.
These findings apply to all rice varieties examined. The exact percentage of arsenic content varies depending on the type of rice. You can find this in the linked study.

Step-by-step instructions: wash and prepare rice

According to research, you should soak and wash rice beforehand. Also, a relatively high water to rice ratio is important for cooking. However, so that you don’t have to use too much energy to heat the water, we do not recommend the 12:1 ratio, but a ratio of 5:1. This represents a good compromise and is also recommended by the BBC, based on the findings of Prof Meharg, one of the authors of the study mentioned above.

Prepare rice correctly – instructions:

Soak the rice in enough water overnight. To do this, cover the rice with water by about an inch.
Drain the water the next day.
Then wash the rice with water until the waste water is clear and no longer cloudy. This not only flushes out arsenic, but also excess starch and any impurities.
Place the rice in a saucepan with water in a 1:5 ratio.
Once the water is boiling, turn the heat down to low. Then let the rice simmer for about 15 to 20 minutes. The exact cooking time varies depending on the type of rice.
Drain the cooking water and drain the rice in a colander.

Freezing Eggs: When Does It Make Sense?

You can freeze raw eggs and store them for up to ten months. If you have leftover egg yolks or whites after baking, you can freeze them too. However, to ensure that nothing goes wrong, you should pay attention to a few things.

Freezing eggs: In these cases it is worth it

You don’t have to freeze eggs to keep them for a long time: raw eggs can be kept in the refrigerator for at least four weeks – provided the shell is undamaged. Hard-boiled eggs will also keep for up to four weeks at a cool temperature. Therefore, in most cases it is not necessary to freeze eggs. Tip: You can use the water test to check whether the egg is still good after the best-before date has passed.

An exception is if you have a lot of eggs in stock or are going on vacation for a few weeks. Then it can make sense to store the eggs in the freezer.

You can also freeze egg yolks or egg whites if you only need part of the egg in a baking recipe. Raw egg yolks and whites would only keep for three days in the refrigerator, but a few months in the freezer.

By the way: When it comes to animal products, organic quality is particularly important. Therefore only buy organic eggs (code 0) – preferably those with additional certification from a nature association such as Bioland, Demeter or Naturland. Also, make sure there is no chick shredding.

Never freeze eggs in shell or cooked

However, freezing eggs can also go wrong. Be sure to note the following points:

Raw eggs in shell: If you put uncooked eggs whole in shell in the freezer, the yolk will expand and the shell will burst. The result: the eggs spread out in the freezer and freeze solid there. A big mess and waste of precious food.
Boiled eggs: In principle, hard-boiled eggs can be frozen. However, the result leaves a lot to be desired: The hard-boiled egg white changes its consistency, becomes rubbery and has a watery taste.

Freezing eggs: step-by-step instructions

If you keep the above points in mind, you can freeze eggs quite easily. The best way to do this is as follows:

If you want to freeze a whole raw egg, you should whisk it well first. Alternatively, you can freeze the egg yolk and egg white separately.
Place the egg in a clean freezer-safe container. Tip: Glass containers are more sustainable than plastic containers. Leave about a quarter of the container empty to avoid bursting in the freezer.
Label the containers with the current date and the number of eggs. This way you will know later when baking and cooking how many eggs, egg yolks, or proteins you have in front of you.
Freezing eggs as ice cubes: If you want to use the frozen eggs in small quantities, you can also freeze them in an ice cube tray and then put them in a freezer bag.

Shelf Life: Whole eggs will keep in the freezer for around eight to ten months. Frozen egg whites will keep for up to 12 months. Nevertheless, you should not store the eggs for too long: the longer they are in the freezer, the more they lose their taste.

Thawing: Frozen eggs should be thawed slowly in the refrigerator. Depending on the quantity, this takes half a day to a whole day. It goes a little faster if you put the container with the frozen eggs in a cold water bath. Under no circumstances should you thaw the eggs at room temperature or under heat.

Use: If the eggs or egg yolks or egg whites are completely thawed, you can continue to use them as usual. Don’t eat frozen eggs raw. Therefore: Heat properly before consumption!
