This topic has been highly debated since the creation of ice cream. In my opinion the best flavor is..... vanilla. It is such a basic but delicious flavor that can be easily be elevated. For example you could add a caramel or fudge drizzle. Or you could add fruits like mango. Additionally, you could also add cereal or pieces of candy for a better texture or crunch. Most flavors have a base as a vanilla and start building it up from there.
