Instant ramen timer
Three minutes is what almost every packet says, and it is right for the fried blocks that make up most of them. The noodles are already cooked; you are rehydrating them, not boiling them.
Pull them at two and a half if you are adding them to a hot broth that will keep working on them, which is most of the time and the difference between noodles and mush.
Air-dried and fresh noodles are a different food and want their own timing, usually longer. The three minute rule is specifically about the fried block.
