As someone very interested in food history, I'm very curious about the effects of the Trans-Atlantic trade on local diets. There's certainly a lot of information available about what people in Europe and the Americas were eating prior to 1492, but it's much harder for me to contemplate Hunan and Sichuan cuisine before the additional of chili pepper. When I ask most Chinese friends, most take it for granted that capsaicum hasn't always been a feature of their diet.
So what did the eat before? Obviously Sichuan peppercorn and other peppercorns were around before, but those alone don't quite fill the void for chilis. It makes sense that many cultures in Asia adopted chili pepper as a way of masking the taste of old meat and vegetables, but why did they so readily and liberally adopt this ingredient, which actually causes pain when consumed, when many Westerners still have not accustomed to even mildly spicy food? Was there another "hot" ingredient in the cuisine before that chilis replaced the niche for?
