Couple of things for me.
One is tiny croutons. I don’t see them anywhere anymore. They taste the same but it’s kind of a pain sometimes to keep the big ones on your fork. The small ones were a little more satisfying to snack on too.
Second is Blue Nehi. Never met anyone else that’s tried or heard of it. Damn it was good though. Big Blue is kinda similar but those always taste under carbonated.
For what it’s worth I had it too and while I liked peach much more I remember blue as a cream soda variant. So maybe try some of those and see how close they are
