@Shadrach @Perris (and anyone else, for that matter) - do you ever can what you grow? “Can” meaning preserve in glass jars via heat or pressure canners, a linguistic contradiction that hurts my poor Asperger-y brain.
If you have access to full-flavor ripe non-gassed tomatoes, especially paste-type tomatoes like Romas and San Marzanos, you can cook up a few gallons of your own perfect sauce. There are some canned (tinned) tomatoes and sauces that I mostly like, but there always seems to be the slightest metallic taste. I’m guessing that the acid in the tomatoes reacts with the metal can, something that doesn’t happen with glass jars.
We started doing this during Covid and still do, although we mostly can (glass jars, grrr) tomato salsa, pickles, and chow chow, which I guess is sort of a Southern US veg chutney. It’s classically made with unripened tomatoes and other vegetables that need to be picked when the first fall frost hits.
