Mix well the egg yolks, making sure there are no lumps.
Little by little, whisk in the oil, start with 1 tbsp, later you can add more. It is recommended to stir in one direction only.
After you have incorporated 4-5 tbsp oil, continue stirring with a spoon or with a hand mixer to make the process easier. If you choose to use the mixer, attach only one beater and make sure to whisk in one direction only.
While mixing in the oil, also stir in a bit of lemon juice and salt from time to time.
You can stop stirring the mayonnaise when you reach the quantity you need. It can be more, or less, depending on what you are cooking.
At the end, add the mustard and adjust with salt or lemon juice if needed.

Stir well. Mayo is ready to be served.
Extremely delicious and fluffy.
