The Tepin or Chiltepin is from Mexico and is the official chilli pepper of Texas. It’s one of the oldest chillies in the world. Jesus would have been snacking on this one. In fact, word has it that it dates back around 7000 years! It has a very hot mouth burn but luckily it dies away fairly quickly. Widely used in cooking Mexican food.
