How to Use a Rice Cooker
You can use a rice cooker to steam large amounts of rice quickly and easily. Measure the amount of rice and water, set the rice cooker to "Cook" and in 35-40 minutes, it will automatically provide you with perfectly cooked rice.
Rice cookers were developed as early as 1912, but the first automatic rice cooker did not appear until Toshiba released it to Japanese kitchens in 1955. Developments in rice cooker technology meant that by 1960 they featured a timer and could keep cooked rice warm. Since then, the rice cooker has grown in popularity and many other companies offer quality models to help the professional kitchen produce large amounts of maximum quality rice with minimum supervision required.
Whether you run a takeaway, a canteen, or a mobile catering company, a rice cooker is a useful addition to any commercial kitchen. This buying guide will provide you with the information you need to make the right choice for your business before making a purchase.
VIEW ALL RICE COOKERSHow Does A Rice Cooker Work?
A rice cooker works by gently steaming rice, controlling the heat and timing, then keeps it at the right temperature for you. While the rice cooker does not speed up the rice cooking process, its ability to cook rice automatically means once the rice has been measured and washed and the water added, the cook is free to carry out other tasks during service. Some of the larger appliances are capable of producing up to 92 portions at a time.
Robust and easy to use, a rice cooker is made up of a non-stick bowl, a heating element and a thermostat control - which is how a rice cooker knows when to stop cooking. Rice used to need all of a cook's attention, but using a rice cooker means supervision is unnecessary.
How to Cook Rice in a Rice Cooker
Cooking rice in a rice cooker is a quick and easy way to produce large quantities of rice. If you want softer rice, adjust the rice to water ratio and increase the amount of water. For firmer rice, add a little less water.
- Measure the desired amount of rice using the measuring cup provided
- Wash the rice thoroughly in a sieve under running water to remove excess starch. This not only stops rice sticking, it also promotes good hygiene
- Pour the rice into the inner bowl and spread it around to ensure even cooking
- Use the measuring cup to add the correct amount of water and place the inner bowl into the rice cooker. As a general guide, use one cup of water for each cup of rice
- Replace or close the lid until it snaps closed
- Depress the lever to the "Cook" position until the light comes on
- Cook for 35-40 minutes
- Once the rice is cooked, the switch will automatically move to the "Warm" position until the light comes on
- Keep the lid closed for 10-15 minutes
- Carefully open the lid to avoid any steam and allow condensation to fall back into the rice cooker
- Stir the rice and serve as quickly as possible
- Disconnect the appliance from the power supply
Please note, exact measurements may vary depending on brand, but this method provides a general guide to cooking white rice in a rice cooker. Brown or wild rice may require more water and might take longer to cook.
TIP: To stop rice from sticking, add a little olive oil with the water.

How to Clean a Rice Cooker
Buffalo rice cookers are easy to clean and maintain, but make sure you use the right equipment.
- Always switch off and disconnect the rice cooker before attempting to clean it
- Remove the inner bowl and wash it in warm, soapy water. It's best to avoid harsh chemicals, but a standard washing up liquid should protect the non-stick coating and prevent rice from sticking
- The exterior of the rice cooker can be cleaned with a damp cloth
- If your rice cooker comes with a water collector, remove by pulling outwards, then wash in warm, soapy water. You should empty and clean the water collector after each use
TIP: To further protect the bowl during cleaning, be sure to use the soft side of a sponge or a cloth.
What is the Difference Between a Domestic and a Commercial Rice Cooker

The main difference between domestic and commercial rice cookers is size. Commercial models are designed to produce a larger output.
- Warranty: Commercial rice cookers are designed for everyday use in a commercial kitchen. Their components are professional-grade, making them much more durable than their domestic counterparts. And a commercial warranty means you're covered for business use.
- Quality, Quantity & Speed: Commercial rice cookers are specifically designed with your business in mind. Fully automated and able to produce much larger volumes, they allow a business owner to profit on time, money and space.
- Return on Investment: A commercial rice cooker can produce large quantities of rice quickly, allowing your business to turn a fast profit. As a guideline, a 10 Litre Buffalo rice cooker costing £199.99 (excluding VAT) can produce 92 250g portions of rice. If each portion is charged at £3.20, your takings would be £294.40, offering a potential profit of £94.41.
