Maybe I'm in the minority here (hurr) but I believe spicy food should accentuate food, not be the flavour of the food.

For example if I eat food and I just pass out from pain (non-sweet gingers, deliberately spicy vegetables / spices, horseradishes like wasabi) or start screaming into the washroom, I'm not going to like it. If I taste NOTHING but spicy, I am going to wonder if the people who eat this every day can even taste the sublime wonder that is white rice. o__O what?
