5: Finish by adding 4 tablespoons rémoulade dressing. Mix well and check the seasoning. For a more attractive presentation, scatter a few chive flowers over the top.

Remarks
The mussels can be pre-cooked either very simply ("à la marinière"), or with more flavour, such as "à l'escabèche" (a tangy Spanish method with vinegar). You can use a simple mayonnaise or rémoulette dressing instead of the rémoulade.
