I sometimes enjoy going through the fridge when cleaning (as well as right before I'm leaving the house for an extended period and immediately proceeding yet another move from house to house) and mixing unlikely ingredients together. Sometimes it works brilliantly, resulting in an awesome combination. These recipes are almost always forgotton afterwards.
Other times it turns out interesting and edible. Occasionally, it is rendered inedible to the point where it induces a violent gag reflex. If you are feeling less daring than I, then I would highly recommend this resource. It would also be a good thing to use when you ask someone "what do you want to eat?" and they reply with "I'm OK with anything."
Then again, I would be inclined to be more creative with strange ingredients when faced with such ambivalence.
That sounds hard. Well good luck on designing it.
