In the USA we typically refer to each type of "pepper" by its name. Papariki, to my knowledge, is limited to dried and ground spice. We have an abundance of peppers here. They are different in appearance and level of heat. Bell peppers are the big roundish looking ones with no heat. Jalapeño are the hot green ones. Thai chilis, fresno, hatch, serano, habanero and scotch bonnet are some others with medium to scorching hot levels of heat. Needless to say we love our peppers!
