Homemade mayonnaise is a treat. It’s very simple to make, too. Room temperature ingredients are best when making mayonnaise at home. Using an immersion blender makes it such an easy task.
Take out any tall glass (mug or a jar) with a wide enough bottom to fit a hand blender all the way to touch the bottom.
Add the egg yolks (try not to break it) then add the vinegar, mustard, and salt on top of the egg yolk.
Place the blender over the ingredients all the way into the bottom of the jar till touch the bottom, pour in the oil and start whizzing at med-high power and without moving the blender for approximately 20-25 seconds. You will just see the mayo will start forming.
Now, move the blender slightly left , tilt it left, right and slowly upwards but not getting it out into the air. Go downwards again into the jar till reached the bottom again. Go up and down a few more times until you have the mayonnaise all formed. This is it, in 2 min you have the homemade mayo, all from scratch. That includes all the preps and gathering the ingredients. Pretty quick and easy, right?

Notes
Oil used
Avocado oil is my favorite and the one I use the most, primarily because it is a healthy option and it’s neutral when it comes to taste and flavor.
Walnut oil is also a fab option as it is a very healthy oil and it has no flavor.
Olive oil is very good to use, provided it is high in polyphenols, but bear in mind it is bitterish, so your mayo will be slightly bitter; thus, you might want to stick to one of the above oil options.
Eggs
Use as fresh eggs as possible. Use organic eggs ideally procured from a sustainable source like a local farm or farmer's market. I’ve made mayonnaise with store-bought eggs as well in the past, and it was all ok.
Make sure your egg yolks and all the ingredients are at room temperature. This is paramountly important!
