The Intransitivity of Taste: Pickles, Cheese, and Chocolate

Which of these does not belong?

Pickles, cheese, and chocolate: Three ingredients, three possible pair-wise combinations, two really good and interesting tastes, and one impossibly disgusting mouthful of gag reflex (no prizes for guessing which). If I like chocolate with cheese, and I like cheese with pickles, why don't I like chocolate with pickles? I mean, other than the painfully obvious - in point of fact, it tastes even worse than it sounds - why the apparent lack of transitivity?
