rinse grapes and do not dry. They will need to be slightly damp

dump Jell-O mix out in a small bowl

set out a large/wide freezer safe container

one by one, toothpick a grape and roll it out in the Jell-O mix. Use the flat end of another toothpick to remove the grape from the toothpick into the container

repeat the previous step for each grape, until all of them are covered in Jell-O. Be sure the grapes are in a single layer in the container or use a second container

freeze for one hour then enjoy!
