Look for Chipotles in Adobo in cans in the international / Mexican section of your grocery store. Chipotles are smoky and spicy, so use more or less to suit your tastebuds. 1/2 a pepper is good for most. (You may have noticed in the photos above that once during testing I made this with three, yes three, whole chipotles. Only do that if you, like me, have tastebuds that have been conditioned after 5 years of living in Thailand and eating flaming hot curries.)
