Paleo Mayo

This is nothing new, and if you Google "how to make mayonnaise" you'll get tonnes of websites and video tutorials explaining in full detail how to create the gooey goodness.
Reason why i still post this, is because i got increasingly annoyed in shops looking for some "good" (read; paleo) mayo. Even when the label read "olive", the amount of actual olive oil in the mayo was still less than the crap oils like soybean oil, canola oil or sunflower oil. How is it that it's allowed to be called olive mayo then??
Not to mention other ingredients like sugar, wheat starch, corn starch and all sorts of preservatives.
From a previous recipe, i had 2 egg yolks left over and decided to take the plunge.
Before you start, realize this will take some effort and patience (and in my case, a strong wrist)

Ingredients
2 egg yolks
1 tsp mustard
3 tsp lemon juice or vinegar
1 cup olive oil (use mild/light olive oil, not extra virgin)
salt
pepper

Procedure

1. In a deep bowl, add egg yolks, mustard, and 1 tsp of lemon juice or vinegar. I used an electric handmixer until it was smooth.
2. With handmixer running, slowly add olive oil until you form an emulsion. If you pour the oil too quickly, it will separate.
3. Continue to add the oil until the mixture thickens. 
4. Add the remaining lemon juice and mix to combine.
5. Add salt and pepper to taste.

 You can vary endlessly with other ingredients, such as chilli powder, onion, garlic, etc.
