Permanent recipes are in the works. Perhaps instead of an artifact roast he creates the artifact recipe for the roast. Possibly creating the roast with the recipe. When you cook this roast it will have a booster on it's quality and instantly gives the dwarf a happy thought. Recipes will have to be within reason of course, so Platinum pies shouldn't be possible, but Plump Helmet pies should be possible. I find this much more appealing then seeing a sad dwarf staring at the biscuits studded with spikes and engravings of dead dwarves until he starves.
Suddenly, I start thinking of
Atelier Rorona's "Pie Alchemy" section, where, after Rorona learns how to bake normal pies using alchemy, she starts trying to make special "alchemy-only" pies, including "Pie-Meteor", which combines a pie with a meteor alchemical weapon (makes pies start raining from the sky like meteors... for no effect but stickiness), "Dunkelpiet", a pie made of the very rare medicinal flower Dunkelheit, which has no effect because it was baked into a pie instead of prepared, a "Pielixir" with the ultimate medicine elixir baked into a pie (heals for a lot, but it tastes like medicine), the "Ruby Pie", made with a philosopher's stone baked into a flakey crust (inedible, no effect), and the "Living Pie", which screams in pain for being baked, and then attacks its baker for trying to eat it before running away... (utterly useless).
Generally speaking, you only make them for the special ending you get if you can synthesize extremely high quality versions of all of them, and for the fact that the cutscenes you get for making them are pretty hilarious (like Rorona being attacked by a pie, "AAAAA! IT GOT IN MY CLOTHES! IT'S HOT!" "It's saying 'hahaha, suffer the revenge of all the pies you have eaten'" "STOP TRANSLATING AND HELP ME!").
I kind of want to see someone make a piemeteor in DF, though. I can almost imagine someone finding a way to weaponize artifact pie recepies through adding syndrome-laden pie crusts so that when they fall from the sky into magma pits, they release clouds of poison gas at invaders.
