Keep in the freezer, in a covered, airtight container for up to 1 week. Be careful to not let them melt much outside the freezer before putting them up or they will freeze together. You can still eat them this way, but it’s a bit more challenging.
The gummy bears will want to slide when picking them up and transferring them to the freezer, but if you are careful and are ready for them to do that, it’s pretty easy to keep them from sliding around.
Rubber gloves were, by far, the easiest and quickest way to get the soaked gummy bears out of the bowl and onto the baking sheet. You can use a slotted spoon, if preferred, but we had trouble with it breaking pieces of the bears off and it was a bit slower.
It’s important to use the regular gummy bears as they are more resilient to the soaking and freezing. Other types of gummy bears such as sour, etc. didn’t turn out well. Haribo was the best brand due to their harder style gummy bears.
