Ok, let me whisper in your ear...
The secret to great tasting Ranch dressing is the mayonnaise and the buttermilk.
Yup, thats it! You don't need to buy an expensive seasoning packet. All you have to do is mix those two ingredients together and toss in some seasonings from your pantry, and you are good to go!
Send all money saved from this hint to me, ok?!
1 cup mayo
1 cup buttermilk
some minced garlic (or garlic powder)
some chopped fresh parsley (or dried)
some parmesan cheese
not too much dillweed (or fresh would be yummy!)
optional: a little mustard (not too much, maybe 1/4 tsp), finely minced (or shredded) onion, fresh cilantro, whatever you can think of.
Mix the mayonnaise and buttermilk and then add the seasonings to taste. I promise that you will like it.
