Preparation time: 5 minutes

This mayonnaise can be used "as is," or you can give it a personal touch:

• add a pinch of curry and serve with fried mushrooms or chicken
• blend in a little tomato paste to make a "Marie-Rose" sauce for cold shrimp
• fold in capers and some chopped dill to serve with fish, etc.

1. In a bowl, mix the egg yolk and the mustard together well;
2. slowly drizzle in the oil, whisking constantly, in order to achieve a smooth and creamy consistency;
3. add the lemon juice (necessary to make the mayonnaise white);
4. season to taste
