Bring a pot full of water (at least 5 cm deep) to the boil. Reduce to a very low gentle simmer.

Line a ramekin, mug or teacup with a large square of plastic wrap. Spray or brush the inside with oil. Crack in your egg.

Gather together the plastic wrap to make a little sack with your egg inside. Twist up the plastic wrap to seal and tie into a knot. If you’re doing more than one egg you can lift the little bag out and set it aside to do more eggs.

Stir the water in your pot with a spoon to create a whirlpool and lower your egg into the centre. This will help the yolk to go more towards the bottom.

Place the lid on the pot. Cook 2 ½ - 4 minutes for runny yolk. Keep an eye on your egg as the strength of your simmer can add or shave a fair amount of cooking time.

Remove to paper towel to drain water off.
