Just wait, roadster! If I can get a good growing season, I'll send you some Caribbean Red relish. Nobody eats it except me. Others have just dropped out. The flavor is wonderful, and it is a fantastic ingredient in sauces and marinades, but it is simply too hot for most people to put (neat) on hot-dog buns or hamburgers.
Hotter and hotter chilies may emerge, but at some point, that escalation is moot, because most people can't eat the products.
