This is the recipe I use for just the 2 of us.(lighter on the sodium than my other recipe using anchovies, which I make when I have a lot of people.) It has just the right amount of tang and I double the recipe and keep it in the 'fridge until needed. I also use low-fat mayo. Jan.
Edited to add: this recipe is in TOH 2005 Annual, Pg.270, for those who have the book.
