Ingredients
- 1 egg
- 2 tsp mustard
- 2 tsp vinegar
- 1 lemon
- salt
- 150ml vegetable oil or more
Instructions
Discard the egg white and place the yolk in a small bowl.
Add mustard and vinegar. Use a fork to mix it all together, then add the tiniest bit of oil.
Keep stirring, not stopping, and keep adding very small amounts of oil. By the time you've used a third of your oil it should be safe to start adding larger quantities at a time. When you get to two thirds of your oil, it's time to start adding salt and lemon juice (I would start with a half and squeeze carefully) and balance out the ingredients according to taste.
