Instructions
Take a tall measuring cup and break the egg in it. You use the whole egg.
Add a heaped teaspoon of mustard. Any mustard you like.
Add a little salt and 1 tablespoon of lemon juice. Immediately add a decent splash of oil to it and turn the stick blender on for about 10 seconds.
Add splashes of oil into the measuring cup and blend briefly in between splashes until the consistency starts to thicken. Repeat until the desired texture. If it is too thick you can add a bit more lemon juice. Too thin you need to add more oil.
