According to Food & Wine, Tropicana has made a cereal specifically to use with orange juice instead of milk! The cereal is called Tropicana Crunch
The box describes it as a "honey almond cereal," and the website explains that it contains honey almond clusters. A Tropicana spokesperson further explained to us that, after testing multiple flavors and textures, the company opted for a granola-based cereal because it can withstand the acidity in OJ better than things like flakes, which would go soggy more quickly. And the honey almond flavor was chosen to balance against the orange juice's tartness. Additionally, the box advertises that it comes with a "paper sipping straw inside," seeming to imply that taste-testers should be willing to slurp up any of the remaining liquid in the bowl.
