Use a piece of lettuce to taste the dressing for a preview.
Combine the buttermilk, lemon juice or vinegar, mayonnaise, sour cream, onion powder, grated garlic, lemon juice, vinegar, fresh dill, fresh parsley, green onion, kosher salt, and black pepper.
If you want to make a tribute to the bottled stuff, use all dried herbs and spices, omit the lemon, and double the vinegar. You can also add a little pinch of sugar.
