Of the five of us, I have the highest... er... tolerance; second in line would be daughter Diana, with a two way tie between Trevor and Tina.
As I have been carefully watching my caloric intake, I try to get a lot of flavor in my dishes. So vinegars, dried chili's, hot sauces, BBQ sauces, Salsa etc. are added to the veggies in liberal amounts. I have come to find that many of the products labeled "Hot" do not live up to the hype.
This could be regional... Last August while in California we stopped at a Taco Bell. I grabbed the Fire Sauce Packet and noticed it actually had some lingering burn! The same packet we get in Oregon cannot do much in that regaurd, unless you let the content of four packets sit in your mouth for a couple of minutes.
