Put avocado oil in a wide mouth pint jar (just big enough for immersion blender) then place in the remaining ingredients.
Place immersion blender at the bottom of the glass firmly with the blade covering the yolk. Start blending and hold there until mayo begins to emulsify and thicken (you will start seeing white at the bottom, 10 to 15 seconds).
Once it starts to emulsify, slowly move the blade up and down in the container till fully combined and all the same consistency.
Stir to make sure it is all mixed together and store in the fridge for up to two weeks. Enjoy!
