Notes
You can use dried or fresh herbs. Whatever you have on hand will work great.
Use a bit less milk for a thicker ranch (or a thicker ranch dip) or a bit more for a thinner dressing.
If you have a basic Oster blender, you can just put the ingredients in a normal mouth mason jar, screw the blender base onto the jar itself, and blend it right in the mason jar.
