1 cup mayonnaise
1/2 cup sour cream
1 clove garlic
1/4 cup fresh parsley, chopped
2 tbsp fresh chives, chopped
Scant 1/4 tsp.salt
Buttermilk (or Futtermilk*) to desired consistency
 
Add mayonnaise and sour cream to a bowl and stir together.  Mince the garlic and sprinkle it with the salt.  Use a fork to mash the garlic/salt into a paste.  Add to the bowl with the mayo/sour cream.  Add in the chopped parsley and chives; stir well to combine. 
 
Stir in just enough buttermilk to reach desired consinstency.  Taste and season with more salt or herbs if needed.
 
 
*"Futtermilk" is what I call fake buttermilk.  It's what I use when I don't have real buttermilk in the fridge...which is most all the time.  Just pour some milk into a measuring cup and add a splash of lemon juice.  Let it sit on the counter for a minute or so and the lemon juice with start to thicken the milk and give it a nice tangy flavor.  Stir it up and use it in place of buttermilk in pretty much any recipe.
