Chocolate alien

What if we encountered aliens and they smelled GREAT?
Maybe they smelled like peanut butter and banana or maybe they smelled like cinnamon toast.

If aliens smelled so great to us, you

    know

someone, somewhere, sometime would find a way to lick an alien or maybe even BITE.
And, then, what if the aliens tasted as good as they smelled? Maintaining diplomatic relations with a sentient race that smelled and tasted delicious to us would be really unusual and probably quite…Challenging.
It is that kind of thing that would make us realize what kind of predators we really are.
