Seeing people talk about cooking plain white rice in the Aroma cookers so figured I’d open up the discussion on this since there’s so many conflicting information out there. From what I understand, the suggested recipe is to add 1 cup (or more) of white rice to the cooker, wash and rinse the rice before adding it to the cooker, then add rice to water in a ratio of 1:1.5 by weight, select the White Rice setting on the cooker and it will take around 40 minutes to cook.
As for the rice itself, does the 1:1.5 ratio change for amounts of rice that is larger than 1 cup of rice? Some say the ratio changes to 1:1.3 for amounts of rice that are larger than 1 cup because the Aroma cooker loses steam as the rice volume increases. Others state that the cook should maintain the ratio of 1:1.5 regardless of the number of cups of rice that are to be cooked. Furthermore, does the rinsing of the rice prior to cooking make a difference in the outcome of the cooked rice? I’d imagine that not rinsing the rice prior to cooking will make the rice come out gummy when cooked. The Aroma cooker does not seem to be programmed to compensate for rice that has not been rinsed prior to cooking. Finally, the 40 minute cooking time for white rice surprised me as I would of thought the cooking time would be less then 40 minutes. The White Rice setting on the Aroma cookers might include a warm-up phase prior to cooking and then the rice will sit for around 10 minutes after cooking to finish steaming the rice to ensure it is properly cooked. This is also the reason you should not lift the lid prior to the rice cooker changing to Warm. Have you all used an Aroma daily rice cooker and have an opinion on whether the 1:1.5 ratio of rice to water is the best ratio to use when cooking white rice, or have you found that a different ratio is needed for best results?

why does the ratio change with volume of rice cooked tho? is it because of the loss of steam out of the cooker as the rice is cooking, or is it because the heating element of the cooker does not reach the top of the pot where the rice is placed? I always wondered about this but never found an answer.
 
The 40 minutes mentioned is not just the cooking time of the rice. The White Rice setting on the Aroma rice cookers will warm up the pot of rice before it truly begins to boil the rice, then the rice will sit for around 10 minutes once the rice is cooked. This is why you should not lift the lid prior to the rice cooker changing to Warm.

Interesting! Does the cheap 6 cup Aroma model also include this warm up and 10 minute resting phase for White Rice settings, or is this only found on the digital models of the Aroma rice cookers?

Only the digital models of the aroma rice cookers that have the actual White Rice button will warm up the rice and then allow for a resting phase for the rice to finish steaming. The models with the mechanical pot do not have a resting phase in that when the rice is cooked, the rice cooker will stop heating and that is when you remove the rice from the cooker.
 
Rinsing the rice prior to cooking makes a bigger difference than the rice to water ratio. I cooked rice both rinsed and not rinsed and the results were night and day. The rice that was not rinsed cooked to a paste while the rinsed rice cooked to perfection. The rice cooker does not make up the difference in starch content of the rice when rice is not rinsed prior to cooking.
