Method
- In a food processor or blender, quickly blitz the egg, lemon juice, salt, mustard, and ¼ cup of olive oil for just a few seconds.
- Turn the food processor back on, and keep it running while you slowly drizzle in the remaining 1 cup of olive oil.
- When you have about ⅛ cup left, pour it all in quickly.
- Transfer to a mason jar or other container with a tightly fitting lid.
