Reasons to use a Rice Cooker

A rice cooker is a staple appliance in any Japanese household and something that gets used nearly everyday. It’s an invaluable and necessary device for anyone who wants perfectly cooked rice without the hassle. Here are a few reasons to use a rice cooker:

• Consistent results: with a rice cooker you can achieve consistent results every time you cook rice so you can avoid burnt bottoms, undercooked grains, and mushy watery texture.
• Simple and convenient: using a rice cooker is very simple and fuss free. All you need to do is add the rice and water, press a button to the setting you want, and walk away. The cooker will handle it all for you so there’s no need for you to keep an eye on it and frees up your stove and attention for preparing other dishes.
• Extra functions: rice cookers also often have several other features. They can keep the rice warm for hours without overcooking, making them perfect for busy households or when timing meals. Many models also come with additional features like steaming vegetables, delay timers, and multiple cooking settings for different types of rice and for cooking other grains such as quinoa. Some Japanese rice cookers also come with bread and cake making functions.

Ingredients to Cook Rice in a Rice Cooker

Japanese Rice

Selecting the right type of rice is crucial for achieving the perfect texture and flavor even when using a rice cooker. Different varieties of rice have distinct characteristics that make them suitable for specific recipes. Long-grain rice, such as Basmati rice or Jasmine rice, is drier and the grains stay separated after cooking making it ideal for dishes like pilafs or alongside curries. Medium grain rice, like Arborio or Carnaroli, is perfect for creamy risottos due to its higher starch content. Japanese short-grain rice, such as Koshihikari, sushi rice or glutinous rice, sticks together when cooked and has a fluffy texture making it excellent for sushi rolls, rice bowls, and other Japanese dishes. Consider the dish you’re preparing and the desired texture when choosing your rice. It’s important to know which type of rice you plan to use because the water amount will differ.

Water

The amount of water can affect the rice texture significantly. Too little water can result in undercooked, crunchy rice, while too much can lead to a mushy, overcooked texture. The ideal water-to-rice ratio varies depending on the type of rice you’re cooking. Japanese style rice (which is generally used when using a rice cooker) has a water ratio of 1:1 (1 cup of rice to 1 cup of water). In a rice cooker, the water not only cooks the rice but also creates steam, which is crucial for even cooking and preventing the rice from drying out. Also if possible, using mineral water (soft water hardness of below 50 degrees) will make the rice taste better.

Equipments to Cook Rice in a Rice Cooker

Measuring Cup

A measuring cup is necessary to ensure precise measurements when cooking the rice. Most rice cookers come with their own measuring cup, which is typically smaller than a standard cup (usually about 180ml). It’s important to use this specific cup as the rice-to-water ratios in the cooker’s instructions are based on it. If you’re using a different measuring cup, you may need to adjust the ratios.

A Fine-mesh Strainer

Some people use the rice cooker bowl to wash the rice but this isn’t a good idea. It can create scratches on the rice cooker’s coating and cause damage and can also break the rice grains. Using a fine-mesh strainer for rinsing rice before cooking is better because it allows you to rinse the rice thoroughly, removing excess starch and any impurities. It also makes it easier to strain out the excess water because the fine mesh ensures that even the smallest grains of rice don’t slip through while allowing the water to flow freely.

A Rice Cooker

A rice cooker is of course the main tool needed. Rice cookers typically consist of a heating element, a cooking pot, and a thermostat. Using a rice cooker makes everything simple because all you need to do is wash the rice and set the machine then press a button and wait for it to be done.

A Rice Paddle

Also known as a rice spoon or ‘shamoji’ in Japanese, a rice paddle is designed specifically for rice. It’s usually made of plastic or wood and has a flat, slightly curved and round shape. This design allows you to scoop and serve rice easily without crushing the grains. Using a rice paddle instead of a regular spoon or fork helps maintain the texture and integrity of the cooked rice.

How to Cook Rice in a Rice Cooker?

 1. Measure the Japanese Rice

Use the measuring cup that came with your rice cooker. Scoop the cup of uncooked rice from the rice container and carefully level the uncooked rice with the back of a butter knife or something similar. One measuring cup is 180ml which equals 150g of rice. I don’t recommend tapping the bottom of the measuring cup to remove any air pockets because this will make the surface slightly indented and make you think to add more rice. But this is a bad idea because it will probably add around 10g more rice and then the water to rice ratio will be off. The best way to measure the rice precisely is using a scale and measure 150g of rice.

2. Rinse the Japanese Rice

Rinse quickly once first to avoid soaking up any cloudy water. Place the measured rice in a fine-mesh strainer and rinse in cold water in a mixing bowl (do not use the rice cooker’s internal pot) to remove excess starch. This first rinsing of the rice needs to be done fairly quickly as it is said that the dry rice absorbs 70% of the first rinsing water. We don’t want the rice to absorb too much of this water.

3. Wash the Japanese Rice

With modern rice milling techniques, today’s rice is sold in a nearly pristine state, free from most impurities. This means vigorous scrubbing is no longer necessary when you wash the rice. In fact, applying too much force when washing rice can be counterproductive because it can potentially damage the rice grains and compromise their taste. A gentler approach is now recommended to preserve the rice’s quality and flavor.

1. After draining the rice from the first rinsing process above, gently squeeze and release rice grains about 30 times in the washing bowl without water. This gentle hand-squeezing process helps remove any remaining bran and excess surface sugars from the grains. It’s crucial to drain the water completely before this step. Attempting this process with water still present will prevent the necessary friction between rice grains which makes the cleaning ineffective. Without water allows for better contact between the grains which helps to remove unwanted particles and residues from the rice surface.
2. Rinse the rice by changing the water only a few times. Be mindful not to over-wash, as excessive rinsing until the water runs completely clear can strip away flavor from the grains.

4. Adjust the Water Level

Put the rinsed rice into the inner pot of your rice cooker. Add water. For most Japanese white rice, use a 1:1 ratio of water to rice (e.g. 2 cups of water for 2 cups of rice). Check your rice cooker’s instructions for specific ratios for different rice. Check the water gage in the rice cooker’s inner pot and adjust the water level. Many rice cookers have water gages in two locations. Place the inner pot on a level kitchen bench surface and check the water by both gages for more accuracy. Also, if you look at the scale from above, it will shift and you will not be able to measure it correctly. Be sure to lower your eyes and look at the scale as closely as possible.

5. Let the Rice Soak

Cover the rice cooker inner pot with plastic wrap to prevent fridge odors from affecting the rice. Soak in the refrigerator for about an hour. This cold environment allows water to penetrate the rice grains fully. This method also ensures thorough hydration of the rice, which creates a better texture when cooked.

The cold soak and careful rinsing and washing process can significantly improve the final quality of your rice cooked in a rice cooker.

6. Cook : Select the Cooking Setting

Pre-soaked rice: for rice that’s been pre-soaked for an hour, choose the “fast cooking mode” on your rice cooker. This is because regular cooking modes typically include both soaking and cooking times. By pre-soaking in the refrigerator, you’ve already completed the soaking phase. Be cautious when using normal cooking mode for pre-soaked rice. It can lead to excess moisture in rice due to excess water absorption. 

No pre-soak: if you have chosen not to do the pre-soak in the fridge, you can select the standard cooking mode.

Press the start button or switch to begin the cooking process.

7. Let it Rest

Most rice cookers will automatically switch to “keep warm” mode when the rice is done. After your rice is fully cooked, immediately disable the rice cooker’s keep-warm function and allow the rice to rest undisturbed for 5-10 minutes. This resting period is crucial, especially if your rice cooker lacks a built-in steaming function. However, if your rice cooker is equipped with a dedicated steaming function, you can skip this resting step, as the cooker will handle the moisture redistribution automatically. So, it’s safe to open the lid and fluff the rice right away.

8. Fluff and Serve

After the rice has finished steaming, follow these steps to achieve perfectly fluffy and delicious rice:

1. Open the rice cooker lid and cut the rice crosswise. This allows air to circulate through the grains making them firmer. Then divide the rice into four sections.
2. For each section:
   – Use a rice paddle to lift the block from the bottom.
   – Gently turn it over.
   – Carefully loosen the overturned rice.
3. Repeat this process for all four sections.

How to Store Cooked Rice

Properly storing leftover rice is crucial for maintaining its delicious taste and ensuring food safety. After cooking, rice tends to lose moisture rapidly, so it’s best to set aside only the portion you plan to eat immediately and freeze the rest promptly.

For larger batches of cooked rice, you should wrap it in plastic while it’s still warm. To retain the heat and flavor, you can add a layer of aluminum foil over the plastic wrap. The aluminium foil serves a dual purpose when freezing rice. It helps the rice cool down quickly which helps it to freeze faster. This method of wrapping also helps protect the rice from absorbing flavors or odors from other foods in the freezer.

To enjoy frozen rice at its best, start by thawing the wrapped rice in the microwave for approximately 90 seconds. After this initial heating, open the plastic wrap and use chopsticks to gently separate the rice grains. Then, reseal the wrap and heat it once more. This two-step warming process will make the rice taste more fresh like newly cooked rice.

Serving Suggestions

Plain cooked rice is a staple in Japanese cuisine that can be eaten plain or with added toppings for extra flavour. Here are some suggestions:

Umeboshi (Pickled Plum) :

Place a single umeboshi on top of your rice for a tangy, salty kick. Its vibrant red color also adds a beautiful contrast to the white rice. Umeboshi is not only tasty but also believed to have health benefits in Japanese culture.

Kombu Tsukudani :

Serve rice with some kombu tsukudani for a savory, slightly sweet flavor. This seasoned kelp adds a nice texture and is packed with umami. It’s a great way to incorporate sea vegetables into your diet.

Furikake Rice Seasonings :

Shake some furikake over your rice for an instant flavor boost. These dry seasonings come in various flavors like nori (seaweed), bonito (fish), egg, and more. They add both taste and texture to the plain rice.

Salmon Soboro :

Top the rice with salmon soboro for a protein-rich option. This finely flaked salmon is seasoned and cooked to perfection to add a delicious flavor to the rice.
