You can make your own Ranch Dressing. Buttermilk and a Ranch seasoning packet. This is how people did it back in the 70s when salad wasn’t invented. You can also make Ranch dip with Sour Cream and a ranch seasoning packet.
This seems to be right on the edge of a forgotten skill.
Bonus Tip- you can make onion dip with powdered onion soup packet and sour cream.
Make it fresh.
