What sort of enchanted ice cream/soda pop would wizards/clerics make anyway?
A good starting point in this topic might be to read 'A Face Like Glass' by Francis Harding. But, enchanted food has a long and varied history in myth and fairy tales. Consider the tarts in Pixar's 'Brave', or the poisoned apple in Disney's 'Sleeping Beauty'. Pretty much any effect that a potion can have can be mingled with food (presuming sufficient skill in potion making and crafting food). But of course, fanciful foods would also be created specifically to have pleasurable effects - from the recollection or creation of pleasant memories, to various sensory stimulations, to illusionary vistas, to actual narcotic effects. When you consider what lengths people go to in the real world to stimulate a jaded palette, it's easy to imagine that magicians would be called on to provide fanciful foods of all sorts.
Some food for thought:
1) A frozen treat that erupts with hot toppings like a miniature volcano.
2) A blended beverage in which people can see glimpses of far away lands among its swirling fluids.
3) A pudding that grows sugar crystal plants, with unfolding petals and blossoming flowers.
4) A spiced wine that causes one to re-experience pleasant memories of ones youth when sipped.
5) A potent beverage that forms small storm clouds above the goblet that contains it.
6) A fizzing beverage that occasionally shoots off small raspberry flavored fireworks and pinwheels, which guests try to catch on their tongues.
7) Balls of flavored ice which when prodded, transform into various fanciful shapes like fruits, mice, grasshoppers, and forth.
8) Pies that release clouds of pleasant aromas that stimulate the appetite, and which magically become the flavors the eater likes best.
9) A covered dish of curling steam, which if caught on the tongue can be chewed with illusionary satisfaction, and captures the flavor of various exotic dishes - but which fills the stomach not at all.
10) Small cakes, which if shared, allow the eaters to briefly experience the experiences or perceptions of their fellow diner.
11) A salad made of tossed daydreams, which causes the diner to become lost is a series of pleasant fantasies.
12) Distilled joy, pleasure, hope, courage, or other emotion.
