Why is the first step to place candy in a plastic bag?

You're right, placing candy in a plastic bag isn't usually the first step in any common process.

It's likely you're thinking of a specific scenario that you haven't shared. To help me understand what you're asking, could you provide more context? For example:

* What are you trying to do with the candy? Are you making a treat, storing it, or something else?

* What other ingredients or steps are involved?

Knowing more details will help me understand why you're asking about placing candy in a bag first.
