these two are quite similar; I recently made boiled eggs for the first time in ages, since I was cooking pasta and had some ready hot water to hand. Because it was already hot, my normal timing wouldn't have worked, so I guessed it and got them soft boiled rather than halfway which I usually like. Well anyway, they were delicious, but it did strike me that they're quite similar in many ways to poached (once they're peeled).
No way to mess up the egg (I've only managed to sucessfully poach one egg out of 4)
Doesn't matter much how clean the water is (as in you can re-use a pan)
Can do multiple eggs at once
Perfectly curved, but not egg shaped (due to its liquid center)
Very time consuming to peel
Very quick to cook
Can go straight from pan to plate (important for things that may be cooling)
Easy (for me at least) to mess up
Looks a bit messy
What we need is some kind of soluble bag to hold the egg together briefly when poaching.
