This hot sauce reaches the Extra Hot level on our internal heat scale. The first ingredient in the sauce is chipotle peppers which are made from fully-ripened red jalapeño peppers. This leads to the heat difference between the jalapeno and the chipotle peppers. As chilies ripen, the amount of capsaicin in them increases as well. Capsaicin is the compound that causes the heat in chili peppers, so these mature red chilies are going to be tapping out at the upper-end of the jalapeño’s heat index. Are you ready for the heat?
