This sauce is often served at taquerias. It is a thin sauce and served with burritos, tacos etc.The first time I had it I loaded my tacos with it thinking it was like Anerican style guacamole. It was so hot, I had to throw my tacos away and order more. Now I know to use caution with this. Leave the seeds in the jalapeno, or take them out depending on your desired level of heat. Since you never know how hot a jalapeno is until you take a bite, please start off with just a little jalapeno and add more to suit your taste.And if you are really brave you can add more than one!
