2cup rice with 4 cup water. Why is the water boiling out of the cooker?

Denise, I have owned Hitachi rice cooker since 1978. I wish they still made them for the USA, To answer your question, the Hitachi measuring cup is not a cup but 3/4 cup. I just measured mine and give or take a few grains of rice, 3/4 cup is the answer. Hope you get this 2 years late.

if you put a 10 cups of a rice rinse it first before you add a water , the measure of the water is equivalent of the cup of the rice.now,put 10 cups of water. then put it on the rice cooker, then press rice cooking, it is automatically turn to "keep warm" after it's getting boiled. wait for about 45mins of cooking.thanks.

All right, this can be a bit confusing. IF you still have the cup that came with your Rice Cooker, use it to measure your rice. Then, inside the cooker there are lines showing how much water to add based on how many of the Zojirushi measuring cups you used of rice. THAT's simple.
IF you DON'T still have your Rice Maker measuring cup you will have to use a 3/4 cup U.S measuring cup. This equals the same amount as the rice cooker cup. For each 3/4 cup of rice you use, add that many cups of water. If you use 3/4 cups of rice twice, then add water to the 2 line.
In other words, a rice cooker measuring cup equals 3/4 cup of regular U.S measuring cups.
Hope I didn't confuse this too much. I hope this helps and if it does, please let Fixya know by rating my solution. Good luck and happy cooking!

Hi,
A rice cooker is just like a kettle that BOiLS water.
Cooking rice is easy, any Asians do it by simple ways, try this, a cup of rice is for 2 person, put water on it and measure it by means of dipping ur mid finger till it reaches the rice, the level of water must reach the first line of ur mid finger. Ur ready to cook!
Thats all!

Generally, with enough heat and good insulation, water will boil. Boiling is caused by non-uniform heating - some spots are hotter.
My wife's slow cooker boils even on the low setting -slowly, but it boils.
Our rice cooker never used to boil until I burned tomato rice in it (OOPs). Don't make tomato rice in a rice cooker.

If you are using regular rice, it is 1 cup of rice for 2 cups of water. Bring the combo to a hard boil and then reduce the heat to a slow simmer for 20min, stirring ocassionally.
If you are using "Minute Rice", it is 1cup of water to 1cup of rice. Bring the water to a hard boil, turn off the heat and add the rice. Cover for 5min. Fluff with a fork.

On this rice cooker to make a perfect pot without overboiling....Use 2 cups of rice and 4 cups of water, When it starts to boil life the lid ONCE and stir and then put the lid back on pressing down to make a seal, The water should not boil over if you follow these instructions, I just made a pot :).....Oh and use the same measuring cup for the rice and the water, Just remeber....One cup of rice = two cups of water!

Put equal amounts rice and water (up to 3 cups only) in liner pot, plug in, put lid on, flip little front switch. 10-15 minutes later it will be done and the pot will switch to "warm" mode by itself. Gently fluff with paddle before serving. You can also add salt or other seasonings to the water/rice mixture before starting.

its very easy if you put 6 cups of rice= 6 cups of water
5 cups rice = 5 cups water ...equal proportion

the ratio is 1:1.

4 cups rice = 4 cups water.

be sure to turn the rice cooker on. just wait for it to say cook!

have a delicious rice meal!
