Fill the mug with water

• Pour water into a mug or teacup.

Add the egg

• Crack the egg into the mug of water.

Microwave for 1 minute

• Place the mug in the microwave.
• Cook on high for 1 minute.
• The water should look misty from the egg white; if it isn't, add another 20 seconds max, checking on it as you go (timings depend on your microwave and settings, so it may take a few trials).

Scoop out and serve

• Scoop the egg out with a spoon — it will be delicate, so be careful.
• Place it onto your toast or wherever you like, season with salt and enjoy.
