Ok, this didn't taste very refreshing, but it wasn't as bad as I originally thought it would be. I had predicted after my first reading of this recipe that this would taste like a Cough-syrup Colada. Well, I am woman enough to admit that it doesn't... but I still wouldn't make it a second time. The peaches are the primary flavour here, and since the recipe calls for canned peaches in syrup, there is a cloying aspect to them that I don't care for. The recipe could be improved by substituting fresh peaches. The instant coffee gives the drink a slightly bitter aftertaste, but I don't find that this flavour compliments or balances the peaches... they just compete. Using a coffee liqueur instead of instant coffee would have added to the overall sweetness of the beverage, but the tastes would blend together a bit better. I thought this would turn out thicker, with the blended peaches and the ice cream adding texture, but it is actually quite thin and frothy. I would have enjoyed it more if it was a little thicker ("That's what she said!"). Crushed ice blended in would have done the trick.
Now, that's just my humble opinion of the Peachy Frosteds. To see its true potential for disaster, you need to combine questionable food choices with questionable personal choices. And for that, we must turn to MWSBET Fan Fiction Theatre! (Warning: Probably not appropriate for children!)
