Pasta smells weird
ChefTalk.com Top Picks
I don't know. It is possible that the eggs turned slightly over night, if it was a warm/humid night then the pasta may have taken a longer time to dry, and it is possible the eggs could have turned. I mean, the thing that smells like bad eggs is probably...bad eggs.
It may just be something like some sulphur gas let off from the pasta when it cooked or something too. I wouldn't worry TOO much about it, unless you get sick tomorrow or something. Then you'll know something was wrong, lol.
Why are you going through the trouble to make fresh pasta and then drying it overnight? Better to use it right away or keep it in the fridge with a damp towel on it to keep it from drying out too much.
