This was my favorite drink growing up, going back even further than I can remember. I would make it in pitchers for home use, I would make it in this 1 gallon cooler/dispenser we used to have (similar to the big Gatorade ones at sporting events, but smaller & yellow), and I would make popsicles in my DC comics popsicle tray. Unfortunately they seem to have discontinued it many years ago, even more unfortunately, nobody else makes a similar drink mix. The closest I can get is bottles of root beer extract, but those are hard to find & pretty expensive.
Aunt Wick’s was a brand of the Jel Sert company, who makes Flavor Aid drink mix, Fla-Vor_ice popsicles, and currently owns other brands such as Wylers (for drink related stuff only, another company owns the Wylers brand in relation to soup mixes and other food items) and Royal gelatin/pudding. Jel Sert must not have gotten the recipes with Wylers because the current Wylers drink mixes are exactly like their Flavor Aid mixes, which is a major shame. Wylers used to be very good, second
only to Kool-Aid. Flavor Aid on the other hand is decent enough in the flavor department, but nowhere near as good as Kool Aid or what Wylers used to be, and their powder formula is horrible to work with. It’s extremely fine powder, which clumps up the instant it touches water. What makes that situation even worse is that they charge several times more for Wylers branded mix than they do for Flavor Aid branded mix, even though the actual mix is identical.
