More soup making problems...

[jame_alec]

Yesterday I made soup again. In the past I had made the pasta with the broth, simmered the veggies separately, and strained and dumped them in. I realized I was probably losing nutrients by boiling them separately, so this time I simmered the veggies with the broth and strained and added the noodles. When I simmered the veggies I covered the pot with a lid.

And now my soup has a very noticeable sour taste. Nothing I put in it was particularly sour or expired... what could be causing this sour taste? And is there anything I can do about it now, or am I stuck with sour soup?

ETA: For the veggies I used a bag of mixed vegetables. It had corn, green beans, several types of peas, and carrots.
