how long do cold sesame noodles last in the fridge?
Maybe mine is made different, but everything I use is stuff that I usually keep unrefrigerated on the shelf. I usually mix up some sauce (mostly soy sauce, chili oil, sesame oil, vinegar, peanut butter, other oils I can't seem to remember) and leave it in the fridge for months. Then when I want a batch of noodles, I just boil, then add some sauce. I usually eat it pretty fast, but I have some that has been in the fridge a week. I read a post from a while back that cold sesame noodles go bad pretty fast. Is that true?
If you are just talking about the sesame sauce, it'll last quite a while in the fridge.
Easily a week or two, if not much longer.
They may not be bad as in unsafe to eat, but I have a feeling they won't be particularly tasty after a week on the fridge. They tend to get dry and pasty. If you decide to eat them, try refreshing them with a little extra sauce, thinned with a bit of warm water.
One week is streching it as they get mushy especially if stored with the sauce. You want to keep them as dry as possible when storing in an air tight container especially after cooking them. Reconstitute them in a colander with hot running water and drain well. Then mix with the sauce.
