Name A Dish/Food/Meal That You Just Cannot Cook Or Perfect!

Up until today mine was poached eggs! No matter what I did they either came out uncooked or hard boiled lol. Gave up even trying them. Till I found this method online lastnight, tried it today and hey presto- perfect poached eggs! 
So what is your food demon!??

( BTW for the eggs - 3-4 inches water in saucepan,bring to full simmer, then turn down to  low simmer. Add tbsp white vinegar to water - to set the whites. Crack egg into cup then slide slowly into water. Repeat with as many eggs as you need. Put lid on, turn heat off and leave for exactly 4 mins. Lift cooked eggs out of water!)

^ Do you keep turning them over as you are cooking them? Most people do that but you shouldn't because each side and into the middle doesn't get hot enough.  You need to cook one side and then the other and not turn them over.

Barmaid, you've reminded me that I do have a potato ricer. Thank you!

David - rump steaks, I guess it depends how you like them. Some like them rare(not me), but some like medium.
