@Bella Dea,
Hello Bella Dea. For what it's worth:
I enjoyed the thin restaurant version of ranch dressing. Disliked thick, buttermilk ranch. Here is a simple recipe, to get you started on making your own delicious ranch dressing.
On the back of a packet of Hidden Valley Ranch dressing, it states to mix packet contents with one cup of milk, and one cup of mayonaise. That is it.
I add a bit of fresh garlic, and pepper to mine.
