Pour some water in to a microwave safe bowl
Add a small amount of white vinegar
Crack the egg into the bowl
Gently pierce the yolk with a toothpick
Wrap the bowl with cling film
Microwave for about 40 seconds on high power
Turn the egg gently and put it back into the mucrowave for 20 seconds
And it's done! Mine is a bit too overcooked here but it tastes good!
