After cooking rice for a dish for the evening I'm presuming I can let the rice cool down thouroughly, bung it in the fridge and it will be alright to eat the next day cold?
There is a reason why I want to do this but I won't bore you with it
You can keep cooked rice in the fridge safely for a couple of days, then reheat in the microwave or use as fried rice. We do this constantly as we eat a lot of rice. We have never had a problem.
Uncooked rice can contain spores of Bacillus cereus. These spores can survive when rice is cooked and they can cause food poisoning. If rice is kept at room temperature they multiply and create bacteria which produce toxins. The only way to eliminate this risk is not to use cooled/reheated rice. If you do use it it should be cooled as soon as possible and in any case within an hour. It should be kept refrigerated until ready for re-use and then heated thoroughly.
I make quite a lot of rice salads in the summer and often cook the rice the day before. I cool it quickly and keep it cool until we eat it, and we have never made anyone ill to my knowledge.
Cook the rice, use what you need for your hot dish, plunge the leftover rice into iced cold water, eat your hot meal, drain cooled rice and place in the fridge.
I had a VERY nasty experience of eating cold rice. Nobody's fault except my own. I cooked rice the day befor, cooled it and made a rice salad which was kept in the fridge overnight. I had a stall at an indoor antique fair and ate my rice salad for lunch around 1.30. It hadn't been in a fridge. Around 6 o'clock I was violently ill; I honestly thought I was dying. The pains were horrendous. So please be more careful than I was.
