Buttermilk Ranch

I've deleted the old post for this because I've played with it for a while- and not that I won't continue doing so - but I think I've got a formula that works better:

• 1/2 cup buttermilk
• 1/2 cup mayonnaise
• dash lemon juice
• 1/4 teaspoon salt
• 1/8 teaspoon black pepper
• 1 teaspoon chopped fresh chives
• 1/4 teaspoon of dry dill (or a teaspoon chopped fresh)
• a small dash of onion powder
• a small dash of garlic powder
  

I'm not really sure about the amount of salt - really I'm not sure about much of this! Except the buttermilk and mayonnaise, chives and dill!! I suspect it will be a bit different every time I make it - maybe add a bit of sour cream? blue cheese? bacon? parsley?
