I’ve made caramel popcorn my Caramell did not set on hard anything I can do to rectify the problem now that the Caramel is on the popcorn

Make popcorn balls. Shape the mixture with butter hands.

You can also bake the caramel popcorn mixture in a 350F oven for about 15-20 minutes, stirring half way through to keep from burning. Might help to dry out the caramel when it cools.
