sauce

I had plans last night to try some of our canned tomato sauce last night. However when we tasted it, there were some strange flavors like beef bouillon or Worcester sauce. It didn’t taste sour or bitter, however it is likely to be 2 or 3 years old. Any advice? Thanks!!!!!!

I am not a talented gardener. I have never had luck with tomatoes and all I want is some sauce for pasta and pizza! This year I've finally got thriving tomato plants. So. Who has recipes? And what's the best way to keep my tomatoes until I have enough to make a batch?
