Donuts in a Can

Fresh warn donuts in a sealed can that heats itself

Four glazed donuts will fit into a wider, shorter version of a Pringles can. To keep the donuts fresh the can will be sealed with a similar metal pull top. To make the donuts warm, the pull top is connected to a tube that is fixed to the bottom and goes through the center of the can via the donut holes. This tube is filled with two non toxic chemicals (determined later) that when combine create heat. When the pop top is pulled off, it triggers the mixture and the donuts become warm after 30 seconds leaving the consummer with fresh, moist and warm donuts.

this could heat them up [AfroAssault, Apr 15 2001, last modified Oct 04 2004]

       MRE cans don't heat themselves, do they? I have a bunch of MRE heaters, and they're a bag that you pour water in...some sort of chemical reaction makes heat and hydrogen. That would probably work, but you'd have to put warnings about how the donuts may be explosive...

       Mmmmm... sounds yummy!

       I assumed he was talking about pre-made donuts which had already been fried, and are now being merely reheated.

       Not all donuts are fried, though. Cake donuts are more dense than the kind you're talking about...Not as good, though.   

       Bagels <GOOD bagels> are actually boiled, not baked.
StarChaser, Apr 17 2001
  

       that explains why they taste like nothing.
tkeyser, Apr 17 2001
  

       Are you insinuating that boiled foods like new England boiled dinner...oh, right. Never mind.   

       I'm not sure that donuts would ever make it as survival food, but as anybody who as ever spent several weeks hiking through the wilderness could tell you, a grease laden donut, cakey or not, cold or hot, would be heaven. Of course keeping them dissolving into a can of crumbs would be another task.

       why hot? why not cold donuts very cold

       And top them with roll-on hollandaise, cream cheese rings, or (yum) spravy.

       You can get croissants in a can, but they are not as nice as they would sound.   

       [Basically it's a large can of dough]

       why not use the handwarmer chemicals?
AfroAssault, Jun 05 2001
  

       You can already get those cellophane-wrapped packages of chocolate-covered or powdered "donuts"; I can see putting those in cans to prolong shelf life (if they don't already outlive most humans).
bookworm, Jun 05 2001
  

       um... bagels: every recipe i saw was you boil them, *then* you bake them (sorta like soft pretzels)...   

       so far as donuts: i thougth this was like canned biscuit, but sweeter and maybe cinnamon-flavored or studded with raisins or something, with holes in them, that you then fry... but this idea *might* work too. but only if you somehow made sure they didn't get weird... sounds like it would involve lotsa preservatives..

       This is a truly grand halfbaked product. Not as good as fresh donuts to be sure, but would certainly be an improvement on the supermarket shelf variety.
Bonarein, Sep 11 2001
  

       I think two items are missing from the original proposal.   

       1)A sealed environment for proper convection. To get the donut nice and thoroughly warm they should be sealed in the carrying device.   

       2)Anticipation!!! The opening of the can is occuring way too soon. If you pop the top and then wait for the donuts to warm it will never happen. You'll eat the donuts well before. I propose a self-popping can. A pull-top or other triggering device starts the warming process. As the temprature in the can rises, the warmed air expands. The engineering would be difficult but based on the temprature and duration(this need not be too finite) the top would pop open revealing warm, moist donuts. Enjoy!

       Ah, like pre-packaged popcorn! In fact, there could be a seperate campers' version that omits the chemical heater and is heated over the campfire or in a solar furnace. When it reaches optimal donutality, it pops open releasing the enticing scent and fatty goodness. Also, without the chemical bit, the can would be lighter, allowing campers to carry them more easily.   

       The self-heating kind would still be needed for people without campfires.

       Following the backpacking/hiking genre of inventions, this could work through an ingenious inner pouch in ones hiking pants or shirt. The donut "can" or similar storage device could be zipped into a pouch near the inner thigh or possibly the underarm. The pursuant hiking activity would generate enough energy (heat) to warm the donuts to the preferred temerature. This could be determined by distance or elevation hiked for example. Then one would simply remove the donut storage device and "pop" open and enjoy!
sharkzfan, Jun 11 2002
  

       I was just wondering how you get them out of the can? I worked as a kitchen hand for a while and I know that dough, water and heat is a recipe for benchtop gluey mess.   

       How about a jaffle iron donut shape with one of those tealight candles underneath, it would be the kind of aromatherapy I would definately go for
