I'm all set to make my first batch and am at the point where I'm waiting for the gelatin mixture to cool to lukewarm and something came up and I have to leave......is it possible to set everything aside and then re-heat the gelatin mixture??? Or do I have to start all over??????

i guess you are using a differnt receipe than i have. I just melt my marshmellows and add in the conf. sugar.

Yes, you can reheat, but make sure that it is exactly lukewarm just before you strain the gelatin mixture in.
