Prepare an equal amount of water to match the volume of the egg. Optionally, milk can be used instead of water for a creamier texture.

Mix the egg and water in a 1:1 ratio. Add a pinch of salt and stir gently until combined.

Strain the egg mixture through a fine sieve to remove any lumps or egg threads.

Prepare a water bath by placing the cup with the egg mixture in a pot with water halfway up the cup's height. Heat on high without covering the pot.

Once the water starts boiling, turn off the heat.
