Have you been missing dairy sour cream? If so, this is one super close replacement.
Open the can of coconut milk and scrape out the cream into a medium sized bowl. Hint: Open the can from the bottom and pour the milk out into a separate container before scraping out the cream. You can use the saved milk for smoothies and other recipes.
If not using right away, place covered in refrigerator until ready to use.
I use Aroy-d full fat coconut milk for this recipe as it really sets up well and has no additives. If buying coconut milk, make sure it has at least 18% fat content.
