Cranberries are incredibly bitter to the average palette. While they have a distinct taste, they need sugar to balance out the bitterness enough to enjoy it.<p>Grapes have the opposite problem. If you&#x27;ve ever wondered why there isn&#x27;t grape ice cream (long shot!), it is because all of the flavor in a grape is in its skin. The center is a generic, unidentifiable &quot;sweet&quot;. That&#x27;s great for juices, where other fruits can add taste, but bad for ice cream. Grape skins don&#x27;t do well in ice cream—the texture freaks people out.
