Take a stick blender and break two eggs in it. Whole, no need to split them.
Add a tablespoon of mustard. I like to use whole grain mustard as it add a bit of extra color to the mix and is just delicious.
Add a little salt and 2 tablespoons of white vinegar. Immediately add a decent splash of oil to it and turn the stickblender on for about 10 seconds.
Open the blender, add another large splash of oil, turn again. Repeat this a couple of times until your mayonnaise has the required consistency. If it becomes too thick to turn around, you can add a little bit of either lemonjuice, water or vinegar to thin it again.
