i do make my own. havnt tried the paleo mayo yet but have made it two ways: 1% milkfat buttermilk, and fat free sour cream, as well as the mayo with olive oil and 1% milkfat buttermilk. if im not gonna give it up, ill at least make it the best way i know how. still a little skiddish of the paleo mayo. but ill at least try it.
Ranch Dressing. Sad, I know.
If you made some paleo mayo and mixed it up with coconut cream and herbs I bet you could make up a pretty good Ranch substitute.
