Grape is likely one of the first fruit flavors. But despite its prevalence in candies and popsicles, it is absent from ice cream.
There are a few valid reasons why grape ice cream is rarely sold, but none of them have anything to do with the absurd claim that the FDA banned it for making dogs sick.
The first has to do with the color of the fruit! Grapes contain anthocyanin, the pigment responsible for their purple hue.
This antioxidant alters how grape puree freezes. Breaking down impacts color and flavor. That's why most grape-flavored pastries contain colors.
The acidity quality of grapes makes it difficult to incorporate them into ice cream. When grapes are combined with dairy, certain chemical reactions will occur.
Grapes have a high water content, making them an easy way to stay hydrated. However, if you freeze them to make ice cream, they will turn into icy chunks.
For ice pops, this is nice and dandy, but for a scoop of smooth ice cream, this is not. It is difficult to manufacture big volumes of creamy ice cream.
There are artisanal ice cream establishments that serve grape ice cream and sorbet. Additionally, homemade grape ice cream is possible.
