I have not yet tried to make MMF with marshmallow creme instead of just melting marshmallows. I read on CC that MMF will be more bright white than off white if you use marshmallow creme instead but I cannot find the thread. If this is true, can someone please tell me how much marshmallow creme you use to replace the marshmallows? TIA.

Good question.. I have wondered about this to

I've never tried it, but I've heard it's not the same consistency as MMF. It doesn't get firm enough to work with.
