I'm on a Japanese food kick after starting Midnight Diner on Netflix, and recently purchased a rice cooker. I'm experimenting with the delayed rice setting, and have programmed the device to have my rice ready approximately three hours from now.
Instead of water, I'm using chicken stock from a brand new, unopened box. I'm pretty sure that there is nothing unsafe about this, but the box does say that unused stock should be refrigerated after opening.
Is there any reason to worry about leaving two cups of chicken stock in a rice cooker for approximately two hours before the machine begins cooking?
