Step 1

Add the egg yolk, mustard, whey, lemon juice, and salt to your blender cup.

Step 2

I use a KitchenAid handheld blender that comes with a special cup for blending. It's awesome for sauces and dressings!

Step 3

Blend on low speed until the mixture is light and frothy. Slowly drizzle the avocado oil into the blender while it's running. As the mayonnaise gets thicker you can move the stick blender back and forth and up and down to make sure the oil is distributed evenly. When all the oil has been incorporated you should have a thick creamy mayo that is ready for eating.

Step 4

Store the mayo in a jar with a tight-fitting lid in the fridge.
