Today’s prompt is to share “a recipe.”
Note that the prompt does not say that the recipe must be for food. It could be a recipe for, oh, I don’t know, non-Newtonian fluid, or glowing water, or something I just discovered, blacklight gelatin.
It might be an interesting effect to fill a brain-shaped mold with blacklight gelatin instead of the usual brain-colored gelatin. There are all sorts of things that one can do with glowing brains. Here’s a suggestion. Make one strawberry, one lime, and one lemon. With the simple addition of a Shatner mannequin, you could create a Star Trek themed haunted house.
