There are, however, a few caveats. Tread carefully: Starburst are comparatively smaller than marshmallows and go from cool to flaming molten goo quite quickly. On a related note, if you are the kind of monster whose preferred marshmallow method is shoving it straight into the flames and blackening it, that's not gonna work so well here. Gentle toasting is the order of the day. Finally, let it cool a bit before devouring, but not so much that it loses its warm, roasted properties.
