A delightful dish featuring tender leeks topped with a creamy mustard dressing and garnished with fresh herbs.
Steam the leeks over boiling water until tender.
Ensure the leeks are evenly cut to cook uniformly.
In a bowl, mix the mustard and vinegar.
Whisk the mixture to ensure the flavors combine well.
Mash the egg yolk into the mustard mixture using a fork.
Mash thoroughly to avoid lumps in the dressing.
Gradually whisk in the olive oil to create a smooth dressing.
Add the oil slowly to emulsify the dressing properly.
Season the dressing with salt and pepper to taste.
Taste and adjust seasoning as needed.
Pat the steamed leeks dry with paper towels.
Drying the leeks prevents the dressing from becoming diluted.
Arrange the leeks on a serving dish and spoon the dressing over them.
Ensure the leeks are warm to absorb the dressing flavors.
Garnish with chopped parsley and serve.
For a vibrant presentation, use fresh parsley.
