Here's a suggestion;
Serve your enemy the best food possible. Caviar, shark's fin,
grilled steak, fresh sashimi. For dessert, let it be ice-cream,
bird's next, extra rich pudding.
And all the while, give as wicked a smile as possible, or as big a
grin as possible.
If that person really hates you, he or she might even be suspicious
towards to you. To the point that they can't even enjoy the food.
Who knows, they may even be paranoid about you poisoning their
food.
