To make mayonnaise:
Crack an egg into a jar.
Add 2/3 cup avocado oil to the jar.
Squeeze juice from 1/2 lemon into the jar.
Sprinkle in a dash of salt and pepper.
Place an immersion blender into the bottom of the jar and turn on. Hold on the bottom for 10-15 seconds, until it starts to thicken, then move the blender up and down until everything is mixed and thickened to a mayonnaise.
