I'm kinda new to cooking and recipes and stuff, so I'm a little in the
dark about a few things. Exactly what do some recipes mean when they
say envelopes? Someone posted a gummy bear recipe and I have no idea
what it meant when it said 7 envelopes. They can't literally mean what
I think they do right?

Please help me, I'm a single who thrives on fast food, I've so much to
learn.
