"This recipe uses cultured coconut milk as a substitution for buttermilk and mayonnaise in a dill-flavored, creamy salad dressing. Enjoy! I found an alternative to dairy-based yogurt. Cultured coconut milk is not as thick as yogurt, but it works as a sub for buttermilk and mayonnaise in a traditional ranch-style salad dressing or dip. It's not a perfect sub, but for anyone who is avoiding dairy, it's worth a try. Look for this product in the yogurt section of your grocer. It's also great in smoothies!"
Whisk coconut milk, parsley, lemon juice, garlic powder, dill, onion powder, mustard, salt, and black pepper together in a bowl until smooth and creamy. Refrigerate until flavors blend, at least 30 minutes.
