1 egg yolk
(or light olive oil)
White wine vinegar
(or lemon juice)
1 Bring the egg and mustard to room temperature in advance.
2 Mix egg and mustard with a stick blender (or mixer) and add the oil slowly in a thin stream. The mayonnaise should begin to thicken. Continue to mix until all the oil has been added and the mayonnaise has set.
3 Add vinegar or lemon juice. Mix some more and season with salt and pepper. Taste, and adjust seasoning, and perhaps add more vinegar or lemon juice.
4 Let the mayonnaise rest in the fridge before serving; this allows the flavor to develop and gives the mayonnaise time to thicken.
