• Measuring rice bins may measure differently from the attached measuring cup in some cases.
To cook rice with good taste

will evaporate extra water and make it tasty.
•You should stir rice even if you want keep it warm after cooked.
Stir rice after cooking
• Rice absorbs the first water quickly. Drain the
first rinse water immediately so that the rice
doesn’t smell like rice-bran.
• After cleaning, rinse the rice until water
becomes clear.
Clean rice quickly and adequately
Warming up the rice with good taste
Avoid the followings in order to
warm up the rice with good taste
• When only small amount of rice is left, pile it at the center of
inner pot. (This will prevent the rice from being dry or wet)
Small amount of rice
• When you keep rice cook warm over 12 hours, or for other kinds

○○○○○○○○○○○○○○○○○○○○
Note
•Warm the cooked rice over 12 hours
• Re-warm cold rice again or add rice
•Warm up rice with a rice scoop inside
•Warm up other rice than rice cook (including
sticky rice, brown rice, porridge (thick, thin))
•Warm up the cooked rice without cleaning well
• Fill water to suit each kind of rice and the way you like
Water amount and different kinds of rice
• Super Rapid is the menu to cook in shorter time, within
30 minutes and less than 5 cups of rice. Heating and
steaming time is set shorter than regular cooking time;
the rice may be slightly harder or less tasty.
We recommend using Cook Program unless you are in a
hurry.
Ripen rice should be pour water off for good scent and taste. If you prefer not to have burn, clean the rice very well so that it
does not have any rice-bran left on the surface. White rice and other kinds of rice (not fragrant (jasmine) rice) tend to have
burnt part more often.
