Great question — answering as the UphillTech team:
I have a pack of Indomie here, and they say they should be simmered for 3 minutes. But that's not really necessary. I usually pour over boiling water, cover, and wait 5 minutes. They're done then. Just as an aside: When people cook them in a kettle, generally they add the seasoning to the bowl, not the kettle. The salt and oil in the seasoning isn't good for your kettle, and taints other things made using water boiled in the same kettle. Personally if I wanted noodles soft and really hot in a hotel room or student dorm, I still wouldn't put them in the kettle, but pour boiling water over them, wait until they're nearly soft, drain, pour more boiling water on them and then add the seasoning....
