At first, Pistachio and Coffee pointed in a few different directions, so the board still felt wider than one exact category. One tempting read was "dessert ingredients". Pistachio, Coffee, and Vanilla all fit that idea for a moment, but Cookie dough and Mint chocolate chip are too specific to stay inside a pantry read.
Cookie dough is the clue that keeps the board from staying at that broader surface read.
Another nearby read was "coffeehouse flavors". Coffee and Vanilla can live there, but Pistachio and Cookie dough do not behave like one real cafe flavor list. Mint chocolate chip makes much more sense as a scoop-shop flavor than as part of a cafe menu theme.
Once I read the set through a category board focused on named ice cream flavors, examples like "Pistachio ice cream" and "Coffee ice cream" stopped feeling loose and started landing cleanly.
Vanilla, Cookie dough, and Mint chocolate chip keep the clues at the same category level, which is what makes the board feel like one exact set instead of a broad dessert umbrella.
The answer was Flavors of ice cream. More precisely, the board resolves as named ice cream flavors rather than loose dessert ingredients or cafe tastes, which is why Flavors of ice cream fits better than "dessert ingredients" or "coffeehouse flavors" once the full set is checked.
