Herb Mayonnaise 

You can use any combination of fresh herbs you wish here. The points to remember are (1) only the leaves should be used; (2) they should be well minced; (3) avoid using large quantities of the strong-flavored herbs, such as rosemary, sage, or thyme. Choose milder-flavored ones, like parsley, basil, or dill. You want the mayonnaise to be fragrant, not pungent. 

Ingredients

1 cup mayonnaise

⅓ cup minced fresh herbs of choice

1 scallion, minced (white and green parts)

1 teaspoon Dijon mustard

1 tablespoon champagne vinegar

In a small bowl, stir together all the ingredients until well combined. The flavor will develop if you let it stand briefly before serving. Keep covered in the refrigerator for up to 3 days.

Makes 1 ½ cups
