Fresh mayonnaise is very simple and quick to make.
1 egg yolk
1 teaspoon mustard
1 teaspoon white wine vinegar
Pinch of salt
Pinch of pepper
1 cup of oil (sunflower, corn, olive, or other)
Place the egg yolk in a deep heavy mixing bowl.
Using a whisk beat in the mustard, vinegar, salt and pepper.
Very, very slowly start to pour in the oil while mixing all the time until all the oil is in.
Because homemade mayonnaise is made with raw egg yolk, you should store it in the fridge, and not keep it for too long. Three days maximum is recommended.
