It's time for me to stop being such a wuss. I need to build up my tolerance to spice. I want to use some chili peppers in food. Teach me about them
Maybe you should learn some Mexican food recipes! Chili peppers actually originated in Mexico. 
Ah.. makes sense. Mexican food is spicy too. What else can you tell me?
The substance that gives these peppers their spiciness when eaten is called capsaicin.
