Simple Homemade Buttermilk Ranch Dressing

"The thing about ranch dressing is it's about a billion times better when you get in in a restaurant than when you buy a bottle. I don't know what they do to the bottled stuff to zap all the flavor out of it, but I recently decided enough was enough and set out to make my own. Turns out we already had all the ingredients for fresh easy Buttermilk Ranch Dressing in our kitchen, and it was delicious. So, so, sooooo delicious! We paired it with some Southwestern Eggrolls and babbled on and on about why haven't we just made dressing at home before now?!"
