Lemon Dill Sauce:
1 cup mayonnaise
1/4 cup buttermilk
2 tablespoons chopped fresh dill leaves
1 tablespoon minced fresh parsley leaves
1 tablespoon grated lemon zest
2 teaspoons fresh lemon juice
1 small garlic clove, minced
Combine all the ingredients in a bowl and stir well. Refrigerate until chilled; the sauce will thicken as it chills.
Yield: 1 1/2 cups
