For anyone trying assorted recipes, the BBC FOOD site has masses of tried and trusted ones, usually with reviews.
Even if you find a recipe from someone else, it's worth checking if that BBC site has something similar.
Of the 'celeb' chefs, I'm pretty sure that Mary Berry and Delia Smith ones have all been thoroughly tested. If you're OK with the more 'throw it together' type dishes, then Jamie Oliver does some decent 'quick' ones, also the Hairy Bikers (RIP). James Martin should also be OK, though I'd likely swerve anything from foreign climes with any ingredients that need faffing about to find??!
[Oh, that point re ovens is a good one, they are notorious for having temp variations!]
