Homemade Ranch Dressing

This is from my sister in law Kelli-

natural sour cream, plain yogurt, or mayo
Add any combination of the following:
garlic powder (or garlic salt)
salt (if not using garlic salt)
pepper
parsley flakes or chopped fresh parsley
dill
onion powder or finely chopped onion
chili powder
paprika
cumin
basil
chives
green onion
cayenne pepper
whatever else is in your cabinet that you feel like adding!

If it is too runny with just the sour cream, I add vegannaise to stiffen it up. Also, if you want it more like salad dressing, you can add milk or milk substitute and throw it in the blender. Add tomatillos, cilantro, and lime for Cafe Rio-type dressing.
