I'm going to make nori wrapped rice on Sunday and give my coworkers a taste at work on Monday. Is it okay to put it in the fridge after making it on Sunday night and bring it to the unit on Monday morning?
Yes, but putting it in the fridge will affect the texture of the rice, so we recommend storing it at room temperature in the winter in a tupperware box (note: store it whole and cut it up when you're ready to take it with you).
It's best to get the ingredients ready on Sunday night and get up a little early on Monday to get it, then it will be fresh and tasty. That way your cooking skills won't be compromised by time.
