I've always considered myself a lucky/confident cook - if I make a mistake I'll find a way around the problem, or, at worst, get it right the next time, but spaghetti carbonara beat me every time. I use the past tense because I gave up years ago trying - without exception and despite all variations I would scramble the eggs. A chap can only withstand so many humiliations. O! were mine eye-balls into bullets turn'd.
