While asked in jest on Twitter about roasting marshmallows over the open lava, USGS Volcanoes officials responded, saying the mixture of sulfuric acid and sugar would lead to a "pretty spectacular reaction."
Erm...we're going to have to say no, that's not safe. (Please don't try!) If the vent is emitting a lot of SO2 or H2S, they would taste BAD. And if you add sulfuric acid (in vog, for example) to sugar, you get a pretty spectacular reaction.

“We're going to have to say no, that's not safe,” volcano officials said. “Please don't try!”
Not to mention the marshmallows would taste terrible, officials said.
