Instructions
Dump all the ingredients into the jar (including the oil).
Wait a sec to allow the oil to float to the top.
Put the immersion blender in the jar, making sure the head of the blender is flush against the bottom of the jar, with the yolk (if using) underneath the head of the blender.
While holding the blender on the bottom of the jar, turn it on full-speed. After a few seconds, slowly begin incorporating more of the oil by slightly lifting the blender from the bottom of the jar.
Once you can see that it is emulsifying, continue to blend until the entire mixture is well-emulsified.
Store the mayo in the jar you blended it in until you are ready to enjoy!

Notes
To make vegan mayo with aquafaba, replace the egg with or 60ml (¼ cup) aquafaba and follow the same process.
Egg safety note:
Whether or not eggs are safe to eat raw seems to depend on where in the world you are eating them (and which governing body is making the rules). Where I live, in Canada, eggs undergo an inspection process before they enter grocery stores making the risk of salmonella poisoning extremely low. In the US, the USDA recommends using egg substitutes instead of raw egg in uncooked applications. If you're unsure about the safety of raw eggs, there is good news! Aquafaba is a fantastic egg substitute for your mayo!
