Dairy Free, Soy Free Coconut "Sour Cream"

As a sour cream substitute, Avocado Cream is really very good. But avocados have been sub-par at the grocery stores lately, Whole Foods included, so I cannot make mock sour cream for any of my favorite foods, which include quesadillas and black bean soup. I keep looking for a dairy free, soy free and nut free sour cream alternative at the stores, but so far nobody has ponied up on that front.
