I've been cooking a certain brand of noodles, and noticed that the seasoning provided is quite salty than you'd expect. Is there a way to reduced the saltiness without a noticeable change in flavor? And if it does change the flavor, please describe in what way it changes.
My simple method is just to use less of the packet. If it's still a little bland, you can always add spices back in (eg, if you want a touch of heat, shake in a little crushed red pepper).
If you're preparing ramen, my uncle's simple method was to stretch it out by adding other vegetables, such as some form of cabbage (eg, bok choy, a couple of shreaded brussel sprouts), some sliced onion, bean sprounts, etc. It's basically a form of diluting, but you're adding things that need to be seasoned, so it won't seem as overly salted.
The only way to reduce saltiness is to dilute it. This will also dilute the flavour. You can, up to a point, mask excessive saltiness with quite a lot of sugar, but that won't work here. Don't believe anyone who tells you that putting a raw potato in whatever you're making will absorb extra salt; this is an old kitchen myth and has absolutely no basis in reality.
If this is dry seasoning, you may be able to physically separate the salt out. Options might include sifting (if the salt is a different size), settling (if the salt is a different density).
You may also be able to perform chemical separation, for example if the salt dissolves in cold water where's the rest of the seasoning does not.
Finally, you could mix your own seasoning!
