Fill the saucepan 3/4 full with water.
Add 3 Tbsps vinegar for roughly every litre (quart) of water.
Bring to the boil.
Once boiling reduce the heat to just below boiling (water should not be bubbling).
You can crack your eggs straight in and allow to cook, although doing this you may break a yolk and pollute the water.
I recommend instead that you first crack the eggs into a cup or bowl and then into the water.
Once the eggs are in the water keep the water as hot as possible without boiling
Cook for approximately:
1-2 minutes for runny
2-3 minutes for soft
3-5 minutes for firm
Remove with a slotted spoon.
Allow to drain and serve.
