    Can marshmallow fluff be used instead of marshmallows in this recipe? I don't eat lard and marshmallows have lard in them, marshmallow fluff doesn't have lard. Thank you!

      Yes it can but you'll need to follow the DKF recipe for kosher fondant http://artisancakecompany.com/2014/10/kosher-marshmallow-fondant-recipe/
