I am not usually a person who buys buttermilk. I most often when baking make my own with 1 tbsp apple cider vinegar and milk.
So to get the tangy flavor that ranch has WITHOUT buttermilk, just use sour cream!
You can use unsweetened plain almond milk, or substitute 2 tbsp heavy cream + 2 tbsp water.
