In some regions of the U.S., piccalilli is a condiment made of finely chopped sweet peppers, pickles, or tomatoes. You might add piccalilli to your hotdog or hamburger at a summer cookout.
The word piccalilli (originally piccalillo) comes from pickle. The earliest versions of these chopped vegetable concoctions were a reinterpretation of traditional South Asian pickle by British colonizers. Piccalilli in all its forms is much less spicy than the Indian version; in England, it's often made with cauliflower and cucumber, and seasoned with turmeric and mustard. Classic American pickle relish is also a kind of piccalilli.
