I tried

I JUST MADE BEEF WELLINGTON FOR THE FIRST TIME EVER 

The Bad:

I bought the wrong cut of beef, so had to trim and trim and trim it
I folded the pastry in incredibly daft ways so it started leaking
I forgot that I needed clingfilm to seal it first and set about panicking
I lost the egg brush thing and so ended up brushing it in the most haphazard way
I couldn't remember how long to time it
I forgot to get thyme
I forgot the garlic
The mushroom paste went everywhere
I couldn't find strong English mustard, just minging Spanish supermarket 'mustard'
I forgot to grease the tray so some of it stuck to said tray
Gordon Ramsay's how-to video is all, 'Beef. Cook. Wrap! Mushrooms. Fridge. Oven. Done!'

The Good: 
It tasted absolutely divine. Shockingly good. Like, OMG.My tastebuds were screaming with pleasure at each mouthful. I was all, 'Ramsay! Why would you smother the beef in mustard and then add some mushroom salsa thing to it? What!'

But it works. Oh, how it works. If I can just not fail on all the other stuff in future, this'll be a perfect dish.
