/////When I cook poached eggs in the microwave, how can I PREVENT the yolk...

[Happiestinthekitchene]

Just do a Real paoched egg. It takes about the same amount of time and will taste Oh so much better.

...from getting hard-boiled as opposed? ...to it being runny like a real poached egg?

 

[RobertS]

It depends on the time & power combination.
Try using less of each when setting it up.

It is up to spit second timing, the power of your oven and the amount of time you leave for it to set.

MW Poached Eggs

Boiled water
Pour water into a bowl (around a dessert sized bowl is ideal).
Add in a dash of white vinegar.
Stir water and crack egg into revolving water.
Place a lid/plate over the top of the bowl.
Skewer the yolk to prevent it exploding in the microwave.
Microwave for approx. 80 seconds (this is on an average microwave).
Drain the egg out of water
