For some time the habanero pepper held the record as the hottest pepper. But it has long since been surpassed by peppers that are several times hotter. That is not to say that the habanero is not hot. It is very fiery. In fact it is hotter than most people can tolerate. But for those that believe "the hotter the better", this sauce is for you.
While habanero peppers are not common, they can usually be found in major markets in late summer. If you are unable to find habanero peppers you may substitute jalapeno peppers which are available year round in most locations (and they are not as hot).
If you can obtain habanero peppers and like their flavor but would like to tone it down a little, you can do so by removing the habanero seeds in step 2 of the recipe.
Caution: You should wear gloves when handling spicy peppers. Avoid touching your face and especially eyes. Avoid breathing fumes of peppers when cutting, cooking or processing in a blender or food processor
