I'd have added garlic, chilli and oragano to the pasta sauce and if I make anything with tinned toms or passata I add a tsp of sweetener to take the bitterness out of the tomato.
My only recent disaster was a smoked haddock chowder. I don't know why I made it because I don't like smoked fish! I want to like it so keep trying but it's a no-go in my house now.
Other than that I made the Kofta curry and it split when I put the yoghurt in. I've found out since that I should use the yoghurt at room temperature, and it worked the next time! (thanks to top tips on here!).
The vast majority of recipes I do work - thankfully, cos it's annoying when they don't, I hate waste :-(
