Yorkshire pudding. Irritating enough, but when you add in the fact that I can do them to DH's recipe, under his supervision, doing everything exactly as he does and the fuckers still sulk in the bottom of the roasting tin sniggering at me, enough to render me incandescent 
A few of the things on here that I can do:
Omelettes and pancakes - have a dedicated non-stick frying pan just for these and a silicon spatula for the omelettes. Don't cook anything else in it and if anyone else uses it for bacon or similar, smack them with it and make them buy you a new one.
Add a few drops of water to pancake batter along with the flour, egg and milk and make it just on the runnier side of where you think the texture should be. When cooking them, give the pan a little shake. If the pancake moves slightly but doesn't make a sound, don't flip it yet. Wait 'til it makes a little quiet rustly, slightly dry sound before flipping it.
For poached eggs it is 100 times easier to do them if the eggs are absolutely fresh - if you have a farmers market, somewhere that sells them at the gate/in the yard or a neighbour with hens that you can get some from they're ideal. The longer an egg is stored for, the thinner and runnier the white becomes. You can't fry a fresh egg properly because the white is too gelatinous, but it's perfect for poaching. Certainly never try it with a box of eggs you've bought and kept for a week or two.
