1/4 teaspoon minced, peeled garlic
1/4 teaspoon salt
1/2 cup buttermilk
1/2 cup sour cream
1/4 teaspoon dried oregano leaves, crumbled
1/8 teaspoon ground black pepper

On a small board, mash garlic and salt to a smooth paste with the blade of a knife. In a small bowl or wide-mouthed 16-oz jar, whisk garlic paste and remaining ingredients until well blended. Refrigerate 1 hour or more while the flavors blend. Keeps at least one week. Dilute flavor, if desired, by adding 1-2 tablespoon each buttermilk and sour cream. Makes 1 cup.
