Contraversial ice cream flavors are flavors of ice cream which are debated as actually being yummy or satisfactory.
Mint chocolate chip is one of the most famous because not everyone agrees that mint tastes good in ice cream. It reminds them of toothpaste.
Another issue is the bright green color...
Pistachio ice cream is often green, but pistachios are not actually green.
The controversy here is due to concern about ingestion of raw cookie dough.
