The consumable appears to be a large backpack. One can put any object inside and loudly declares, while holding the backpack, "If only I had [food item]". Be sure that there are no other items in the backpack, because they will be consumed.
(Note that one cannot request a whole dish; for example, they can order plain macaroni, but not mac and cheese).
Open the backpack after five minutes to reveal the requested food item, whose output weight matches that of the input. The taste of the food will depend on the value of the object. Make sure it's exactly 5 minutes. Who knows what'll happen if it isn't.
On a critical fail, black goo will come out of the backpack, but that’s probably fine because the food looks amazing, right?
On the backpack:
It's easy enough to mistake for any backpack at all, and Delphyrion has not put a label on it. They have lost quite a few beakers and pens to it whenever they mused about their next experiment, as they often reach epiphanies by saying, "If only I had [food item]". Perhaps that's why the artifact works this way.
On food quality:
For some reason the output quality directly ties to the price of food in Orlando. So, put a 5-cent pencil in the backpack, and you'll get a 5-cent quality potato fry*.
Also, yeah, make sure it's 5 minutes exactly. This is a theoretical number; no one has tried to test its limits, hence its reference to Schrodinger.
(On a critical fail, one fails to retrieve the food in time and it is either underdeveloped or spoiled.)
*Food will vanish from your stomach after 2 hours.
On the black goo:
Delphyrion themself isn't sure what it is, nor do they ever remember to analyze it. It doesn't seem to leave any residue on the backpack itself, though it stains quite horribly on porous material including skin. With enough washes it should go away.
If consumed, call the Poison Control Center and pray. Oh hey, is the room spinning?
(Also pray that you are not Dephyrion, the chemist who has had 0 interaction with any religion at all, and therefore still thinks priests can get pregnant.)
On Madness:
One gets uncontrollably angry at the sight or mention of any food that did not come out of the backpack. It feels as if one is running a state-of-the-art restaurant, yet people line up for the nearby McDonald's instead. Delphyrion feels this way towards content farms like 1-minute arts.
