Stir all ingredients together except jalapeno slices and pimentoes until well blended.
Add jalapeno slices and pimentoes and stir gently.
Refrigerate at least 2 hours and preferably overnight to blend flavors.
Notes
To reduce the heat, leave out the diced pickled jalapeno peppers and the cayenne pepper. For a milder version, you can also reduce the amount of chipotle chili powder.
