A random chef has to challenge the iron chefs and the secret ingredient will be guineps. Each of the five dishes would have to feature guineps.
This would be a tough show to do, because I'm willing to bet that Bobby Flay, or any of the Iron Chefs would not know what to do with guineps. And it would take an hour to de-pulp enough guineps to cook something.
That is why there is two fantasies interwined here. The first is using guineps as a viable secret ingredient. The second is Iron Chef Bahamas. A more suitable moniker would be Iron Stomach Chef Bahamas.
