My Welsh gran's method: Small saucepan of water. Bring to boil and lower gas to simmer. Whirl the water with spoon and create a vortex. Drop of vinegar. Carefully crack the egg and lower gently into the swirling, simmering water. Give two minutes to cook. Remove egg with a strainer or ladle with holes and serve. Bit of pepper. Delish.
Of course, boiling water, reduced to a simmer, No lemon juice, vinegar or vortex needed.
Crack in fresh egg. Put a lid on and turn off the heat perfect eggs every time
The key is the freshness of the eggs. We buy from the farm down the road from us and they are no more than 24 hours old, rubbish for hard boiled eggs as the shells won't come off that fresh, but amazing for poached. Simmering water with a dash of vinegar in, no vortex, just pop them in and wait around 3 mins or until they are done to your liking. I hate overly running yolks so leave mine in a bit longer.
I can - my favourite way to eat eggs (especially on crushed avocado on sourdough) but they take ages. I also use Delia's method as a fail-safe one; but I've managed them other ways. Some spectacular erratic results with whirlpool methods!! :)
