My article about the chilli scale at Salad King just went up on Torontoist today. I went with Marcelo to see how spicy "20 chillies" really is: http://torontoist.com/2009/03/hot_or_not.php.
Bottom line was that we're weren't blown away. When we were in India for work, I ate a unbattered deep-fried green chili in one bite because it looked like a green bean. Now that was hot.
