I love hot sauce and spicy foods and I am certainly not alone in that love. Humans have used chili peppers and other hot spices for thousands of years. Hot sauces come from hot chili peppers which were first domesticated by peoples in what is now Mexico about 8,000 years ago and would become a very important part of the diet for folks all over the Americas. Fast forward 7,500 years, the Spanish and Portuguese arrived and they adopted hot chilis into their diet. Within a hundred years hot chili peppers were being traded, bred and altered through selective breeding, all over the world.
