If you're interested, here's how I make ranch dressing:
Take a 1-pint bottle of buttermilk and swig a couple of tablespoons off
the top.
Add 1 finely mashed garlic clove
Add 1-2 tablespoons each (minced):
Cilantro
Parsley
Chives or scallion tops
Salt and pepper to taste
Shake well.
Joy of Cooking calls for the addition of mayonnaise, but I prefer the
drizzlability of omitting it.
And, obviously, if you can't get a 1-pint bottle of buttermilk or if
swigging it isn't an option, you can decant it into another container
that leaves you room for shaking or stirring.
I imagine this would work with yogurt, too.
I think tzadziki would work as a salad dressing, although I've never
tried it. Here's how I make that:
Finely mashed garlic
2 or 3 inches of cucumber, grated
A cup or so of yogurt
Salt and pepper to taste
I imagine you could use water as a sub for lemon juice and add fresh lemon zest
instead. You'd have to figure out what to do with the lemon's juice.
I googled for "lemon juice cleaner" and found some homemade cleaners that
use lemon juice for scent.
