How Does a Rice Cooker Work?

Standard rice cookers have a heating element and a temperature sensor or thermostat positioned beneath the inner bowl, which is made of metal to conduct and distribute heat evenly. They feature one or more simple control switches to commence the cooking process. Once turned on, the bowl begins to heat up, which in turn begins to transfer the heat to the water in the bowl.

The heat brings the water to a boil and coverts it to steam, at which point the rice begins to absorb the moisture and cook. The machine will automatically set the cook time to the proper amount based upon the amount of rice and water used. Once the rice absorbs all of the water, the temperature will start to rise. Sensing this change, the rice cooker will either automatically shut off or switch to a warming cycle.

How to Choose the Best Rice Cooker

Here are some factors to consider when purchasing a rice cooker for your business.

  • What power type do you need? Rice cookers come in either electric or gas options. Which type is best for your business depends on your menu and your kitchen's space and utilities.
  • How much rice do you need to cook? Be sure you know the raw rice and cooked rice capacity of your unit before purchasing. If you choose a rice cooker that is too large, you may experience issues with cooking a small batch.
  • Are you looking for both cooking and warming capabilities? Rice cookers / warmers have both cook and warm modes to streamline your operation and keep the rice at an ideal serving temperature.
  • Do you need it to cook other types of grains? Some units are capable of cooking grits, oatmeal, and noodles, which may be necessary for small footprint kitchens.

Electric vs Gas Rice Cooker

To choose a rice cooker for your operation, consider the quantities of rice you'll need to make throughout a day and the uses of each type.

If you have limited space in your kitchen or you do not have ventilation you can use, electric rice cookers are the best option for you. They are much simpler to operate and maintain, and are ideal when cooking smaller quantities of rice.

Pros
  • Do not require as much heat to cook the rice, making them an eco-friendly option
  • No ventilation required
  • Plug-and-play portability and compact design
  • Easy for any staff member to use; instant operation
  • Requires less maintenance
Cons
  • Non-traditional, indirect heating
  • Less efficient for high-volume operations
  • Electricity may be more expensive

Gas Rice Cookers

Available in natural gas and liquid propane power types, gas rice cookers deliver high heat production that is impractical for small batches. They cook rice by preheating rice grains using a direct flame and then cooking them through with pressure, a process said to result in flavor enhancement. Gas rice cookers are ideal for establishments that cook large quantities of rice each day, such as in sushi bars or Indian restaurants where rice is commonly served with entrees.

Pros
  • Heats and cooks rice faster
  • Preheats and cooks rice using a direct flame; closer to traditional cooking methods
  • May result in a sweet, flavorful aftertaste
Cons
  • More complex operation
  • Requires ventilation under a hood
  • Fuel components require routine cleaning

Tips to Follow When Using a Rice Cooker

Using a rice cooker is simple and they can make your life much easier if rice is something you need to produce consistently and quickly. Here are some tips to follow to ensure your rice cooker makes fluffy rice every time!

Restaurant Equipment
  • Rinse your rice before cooking. It's a good idea to rinse most varieties of rice before cooking. Rinse brown rice once and white rice several times using a fine colander or mesh strainer. In general, rinsing your rice:
    • Removes any debris present
    • Removes surface starch that causes rice to become gummy
    • Ensures fluffy, firm grains that retain their independent form
    • Reduces the amount of foam to prevent bubbling over
Restaurant Equipment
  • Use the correct water to rice ratio. A range of factors affect the amount of water different varieties of rice need to cook. Keep the following in mind when preparing:
    • Bran content, grain shape, and grain size affect water amounts (i.e., intact outer bran requires slightly more water)
    • Read variety-specific package instructions to ensure you're using the correct amount of water
  • Note: the standard ratio is 1 1/2 cups of water to 1 cup of rinsed rice.
Restaurant Equipment
  • Enhance the flavor of your rice. It's not uncommon to add bay leaves, cardamom pods, cinnamon sticks, and other spices directly to your rice cooker to create a rich, aromatic experience. Many people prefer to add a bit of salt, oil, butter, or milk to their rice to enhance the taste as well.
  • Let your rice rest after cooking. Your rice cooker may shut off and switch to warming mode, but this does not mean that the rice inside is done cooking. Letting your rice rest for 5-10 minutes after the cooker has shut off ensures that it has time to finish cooking and allows excess moisture to steam out.
  • Clean up quickly between batches. Cleaning the inner bowl of rice cookers can be tricky, so it's wise to clean up quickly to save time and be ready for the next batch. Remove any leftover rice and fill the inner pan with hot, soapy water. Give it some time to allow food particles to soften and break up. Then use a non-abrasive sponge or towel to wipe the pan clean.
  • Do not peek into the rice cooker. Steam escapes every time you open your rice cooker. Because you're combining rice with the precise amount of water it will need to cook, doing this causes rice to dry out. Keeping track of cook times will help you avoid lifting the lid.
  • Do not use metal utensils to serve rice. Metal utensils won't spoil the taste of your rice, but they may damage the non-stick coating of the inner pan used in most rice cookers. Use plastic servingware to prolong the life of your cooker.

Rice Cooker Accessories

Various accessories can help you get the most out of using your rice cooker. Among them are containers used to hold and maintain the quality of cooked rice and specific utensils ideal for serving rice. Check out some of the most important equipment and accessories below.

  • Sushi Rice Container: A sushi rice container is fully insulated to keep prepared sushi rice at the right temperature and consistency.
  • Colanders: Some colanders are designed with small holes that are ideal for rinsing rice before cooking.
  • Rice Warmer:rice warmer holds cooked rice at the optimal serving temperature without continuing to cook it.
  • Rice Paddle: Use a rice paddle to season and serve rice.
  • Rice Napkin: Featuring a reusable mesh design, a rice napkin holds rice while it cooks, allowing for easy cleanup and thorough drainage.
  • Rice Cup: A rice cup is a traditional Japanese measurement - 1 rice cup equals approximately 3/4 (180 ml) of a standard US cup (240 ml).
