As discussed before here, some kids make the effort to order bizarre combinations at yogurt and ice cream places. But at Maggie Moo recently, I put my foot down: "You can't have a scoop of mint and a scoop of coffee together in the same cup. Why? Because coffee and mint are natural enemies, like the foon and the spork."
The solution was to divide the two between two cups and have brownies mixed into both. I was tempted by the coffee ice cream, but once I tasted it, well, it just can't hold a candle to Better Batter with Butterfinger mix-in.
In your assessment of the flavor spectrum, what other combinations are natural enemies?
