The consumable appears to be two chemical vials. Pour them upon an object or pile of items, and watch as it shifts and molds. This normally takes months or years to research and produce, but who are you to complain? It's food.
After a minute you'll get your 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 (not that you can tell if it takes a bit longer than that). Who knows what'll happen if it isn't.
On alchemy:
Here comes the alchemist chef. Does Delphyrion need to specify that this is a transformation from one object to another? Not really. Do they really like the law of conservation of mass and matter? Nope. Do they know they don't have to do all this stuff to limit themselves? Debatable. They'll just insist that this is for the science, the discovery, the suspense, the funny shenanigans.
On the vials:
They appear to be generic vials of clear liquid when unused, though that's questionable enough in and of itself if Delphyrion ever needs to get it past TSA (not that it's much of an issue anymore, considering the availability of their little stash). Hopefully Delph has labeled these correctly, lest they try to chuck this at someone instead of their signature piranha solution. What is the liquid called, anyway? ...Schrodinger's solution. It either exists or it doesn't. Or maybe it's somewhere in between...
On the backpack:
This consumable used to be a backpack. It was easy enough to mistake for any backpack at all, and Delphyrion had 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, use a 5-cent pencil, 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.
*Food will vanish from your stomach after 2 hours.
