would you use out of date pasta, tin toms

[youfhearted]

which my dm keeps palming off giving me,
ahem,
the toms were only 3 months but the pasta is 18 months.

Yes. You'll notice when u cook it if there's anything wrong

Yes. Often use out of date tinned toms. I probably wouldn't go beyond a year though due to the acidity inside the tin.
The pasta should be fine.
