The dissolved solids in a cup of coffee can be re-
crystallised by evaporation. The dry residue is either a
coffee stain or instant coffee, depending on how you got
there (and why). But a vaguely amorphous perhaps semi-
crystalline dark brown solid.
If you started with a coffee-cup shaped mould
cavity, and
repeated the process of [fill with coffee] - [evaporate off
water], after enough repetitions, you would have filled the
cavity with dark brown coffee evaporite.
Then remove from the mould, and you have a coffee cup,
made of coffee.
This is just a curio. Because it would definitely not be a
good idea to fill it with boiling water, splash of cream and
a spoonful of sugar, and stir briskly. So don’t do that.

Not a mockumercial, really. Is it? [reensure, Oct 10 2021]

Easier to pour coffee into the mould and freeze. |
|

Hmm, a portion of ground coffee, spoonful of sugar and a dash of
cream all precombined and frozen into an attractive cube. The
proverbial "one lump" would then be everything but the water. |
|
| |
Certainly easier [pocmloc], but it wouldn’t achieve
the desired ability to re-constitute into liquid
coffee with hot water. A “frozen coffee” mug
would yield a weak, lukewarm liquid that would
barely qualify as coffee. And it would freeze your
lips as you sipped it. Before it melted and dumped
a puddle in your lap. |
|
| |
So I think you’ll agree, mine is better in that it’s
entirely impractical, poorly thought-out, badly
executed, and probably dangerous. |
|
| |
You could use the frozen coffee mug for drinking vodka |
|

Asking unsuspecting people if they wanted a cup
of coffee and then giving them one of these would
be momentarily hilarious |

The difference between that and actual coffee (what
constitutes an actual coffee seems a topic of infinite
debate) is partly/undissolved solids and volatiles. What
we need is an extract of the volatiles, using something
like difluoroethane. Supply in a pressurized can, like
canned air, and spray at the coffee. The solvent flashes
off in a moment and there you go. |

Business empires are based on this very principle. |
|
| |
I reckon if you compressed instant coffee granules into a
suitable mould under enough pressure you'd then be able to
break out a coffee mug pretty much straight away.
Then you wouldn't need the large number of fill/evaporation
cycles. |
|
| |
If you were to concentrate only the oily solids, you may be able to product a hydrophobic cup of coffee. Could be suitable for iced coffee, if the boiling water and stirring liquefied the oils. |
|
| |
The next thing you know, someone will propose
making two of them... |
|
| |
Ahh. That’d be Two Cups of Coffee. Legendary. |
|
| |
But two of these would be Two Cups *of* Coffee.
Entirely different. |
|
| |
Can I set it on my 'coffee table'? |
|
| |
You might have a coffee break if its not structurally sound. |
|
| |
Thoroughly baked as per product in link. It
happens. |
|
| |
[xenzag] - maybe I'm reading the wrong link. |
|
| |
The Kaffeeform cup is made of plant fibers, used coffee
grounds, wood grains, and biopolymers - entirely different
from what I'm proposing. |
|
| |
And if you do have a coffee break, you'll be needing a coffee fix. |

+ Take this croissant to have with a cup of
coffee.Thanks for turning coffee into art! |
