This is how I like to make my ranch from a mix packet - lightened up, but still quite yummy. If you really want to pack a punch, put in 2T of blue cheese crumbles.
- Whisk together the sour cream and mayo. Add buttermilk and whisk together. Add ranch dressing mix and whisk until combined.
- Pour it in a jar, tighten the lid, and place in the fridge for about an hour or more to thicken.
