NYT Connections Purple Group Hint

The purple group is the hardest one, so don’t kick yourself if this visual hint does not immediately take you to the promised land.
Here’s your verbal clue: You’re a whiz if you get this one on the first try, but Whiz doesn’t count.
Crying uncle? OK, that was a vague clue, especially since Whiz would come at the end of this missing-word group, not the beginning.
Today’s purple group answer is ___ Cheese and its words are COTTAGE, CREAM, GOAT, and STRING.
Have a great week, Connectioneers! See you next Saturday.
