Water and Heat Resistant Marshmallows

Marshmallows that can survive in a cup of hot chocolate

I make the hot chocolate. I put in the marshmallow. The marshmallow melts. I want the marshmallow to last a little longer. So we need either hot chocolate that is less hot and wet, or a marshmallow that can withstand heat and water. The latter seems much easier.

       "Trick marshmallows" that can't be roasted would be a novel idea.

       Maybe a bigger marshmallow would last longer. Or a time-release marshmallow capsule. Or use little marshmallows and put them in one-at-a-time on as as-needed basis.

       I thought the point was to melt the marshmallows. Oh well.   

       You could :
1) Let them go stale.
2) Varnish them.
3) Dip them in liquid nitrogen.

       I think [phoenix] 3) answers the need quite nicely. Or just keep marshmallows in the freezer.

       Perhaps marshmallows made of concrete would work. But they wouldn't float.

       Pumice - boyant, heat resistant, and crunchy!

       The current melt time is perfect. You just have to wait until they are about haf melted and slurp them up for maximum enjoyment.

       That would be asbestos, methinks.

       //"Trick marshmallows" that can't be roasted//   

       Why can't they be roasted? Are they made of something explosive and blow before they get brown? I wonder if you can treat marshmallows like cotton with nitric acid etc.

       I haven’t tried this myself (give me a few hours), but it may be possible to irradiate your marshmallow with sufficient gamma radiation to cross-link it. Any cross-linking, of course, will raise the melting point. Eventually, it will never melt. It might char and burn, but it won’t melt.

       Perhaps if they were injection-molded in some multi-cavity press they would have a dense enough shell to resist the cocoa.   

       You ever wonder how they actually make marshmallows? Neither do I. They always have that cylindrical shape. Extruded perhaps?
RayfordSteele, Sep 08 2003
  

       A marshmallow like the ones that come in Lucky Charms cereal but bigger and of a different flavor like mint, or cinnamon might stand up to hot cocoa.

       This would be like making ink-proof paper* ... or water- and heat-resistant condoms*. I, for one, will stand up for our humble marshmallow, who willingly undergoes such extreme conditions for our enjoyment and satisfaction while maintaining a sweet and soft temperment.   

       Oh marshmallow! Listen not to these philistines, who fail to appreciate your subtle sublimation and intricate imbuement, who fail to behold the majesty of your baking as they indiscriminately devour such tender transcendence. Nor, I implore, should you despair as they turn, in idiocy, to those artificial and contemptible substitutes; lest your sweetness sour and aroma acerbate.   

       No.

       I read somewhere about a kid who invented a coating for crackers to keep them crunchy, even immersed in hot soup. Perhaps you could imitate that? +

       Cannibals coined the term "Crackers".

       Protect your marshmallows with cute little neoprene cots --in neon colors.

       No more roasting over a fire?(tears falling)

       i like when my marshmallows get melty in the cocoa! If these are water and heat proof will they still dissolve nicely in your mouth? You could just eat your marshmallows on the side. Take a sip of cocoa, then a bite of 'mallow...and so on.. [wombat] They have mini dehydrated marshmallows that come with hot cocoa packets, that are the same as Lucky Charms marshmallows. It would be cool if you could just buy those by themselves in bulk though and i like your ideas for flavored ones. Big ones would also be cool.
