My two favorite flavors were chocolate and tapioca. One time I recall I even had the opportunity to mix them together at a sleepover at the home of a friend whose parents were far more permissive with processed snacks.
Now, since I'm a grownup (albeit not necessarily always mature) I can have Snack Pack pudding whenever I want. And while these days I'm inclined to make my own large pearl tapioca with fancy vanilla or whip out some high-grade gourmet dark chocolate for pudding, there are times when the sweet nostalgia that comes with Snack Pack is just what I crave.
