Thanks, but I’m only just working the problem. Usually, it takes real insight to conceive the question.
So to work the problem some more… the "SugarStix"TM could be made similar to M&Ms, to melt in your coffee but not in your hand. As we know, the candy coating on M&Ms were invented during WW2 to keep the encased chocolate from melting or from becoming stale. This made the confection easy to pack around, even in the deserts of North Africa. The way to do this would be to design them to dissolve only when the temperature was >120F. That way, no reasonable environmental temperature would melt them, but they could be used in a hot cup of java.
