Canned tomatoes? Yikes. If you’re trying to beat premise sauces at least get some local fresh tomatoes and have a go and making it from scratch. The acidic flavour of canned tomatoes is horrible in my opinion compared to fresh tomatoes.
The good stuff spoils pretty quickly, too. It's not just the price that makes them uncommon
(Also there's canned and there's canned.. it's worth paying for unless you just want red broth.)
canned whole tomatoes > tomato sauce
