Techincally, they’re not really poached because they don’t come into contact with the cooking liquid. However, there’s no vinegar taste from the liquid and they keep a nice shape. (The pan also doesn’t need washing.)
- melted butter
Bring a pan of water to a simmer.
For each egg, you’ll need a square of plastic wrap and a piece of kitchen twine. Butter the plastic wrap and lay it into a ramekin or coffee cup. Crack an egg into the plastic wrap and then twist it shut and tie off with the twine. I like to leave just a little air space so that it floats–without the airspace, it can sinke and the bottom of the pan can melt the plastic wrap.
Put the wrapped eggs in to simmering water and leave them for about 6 minutes (less if you like a runnier yolk, longer if you like it firmer). Pull them out, cut the string, and turn out onto the plate.
