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 one minute 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 1 minute. 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 1 minute exactly. This is a theoretical number; no one has tried to test its limits, hence its reference to Schrodinger.
(On a critical fail, the food appears perfectly made, perhaps too perfect. Ignore the black goo.)
*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 Delphyrion, the chemist who has had 0 interaction with any religion at all, and therefore still thinks priests can get pregnant.)

Anyone watching will see the contractor reach into their pocket and pull out a set of balloons, they can either be brightly coloured and patterned or the expected colour of what they have selected. They inflate each of them using their mouth then twist them together to represent the shape of what they have decided to make. Once this has happened the balloons slowly deflate with the usual whooshing sound. In place of what was once the air that inflated the balloons is the item the balloons represented. The item takes on the colour of the balloons used to make it. The rubber of the balloons appears to absorb into the item after deflation.
