Cornstarch was added to this dip to compensate for the nature of the dairy free ingredients which are not always as quite as thick as their dairy counterparts. This dairy free buffalo dip will appear relatively thin prior to baking it, but don't fret it will thicken as the cornstarch heat. Allow the dip to rest for about 5 minutes after removing it from the oven, this resting period allows it to thicken up nicely.
