Blackberry fondue is a lovely and healthy fondue that is great for berry lovers. It is made from pureed blackberries along with cream and sugar. Some recipes call for the addition of framboise which is raspberry beer to the fondue just before taking it off the heat. Corn flour starch is often added to thicken the blackberry fondue. Blackberry fondues can be used for dipping fruits, crackers or meringues too.
