I've made a batch of MM fondant and it is an ivory/off white color but I would like for it to be white for a wedding cake this weekend. How can I salvage this batch? What can I do in the future to prevent this from happening?
Try using the marshmallow cream in the jar instead of the regular marshmallows... it makes a nice white fondant. Here is some more information for you....
There is nothing wrong with your MMF. Marshmallows have a yellow twinge to them when melted. So MMF will always have an off white color. Wilton sells a White White Icing color. That will help brighten it a little. I have also read that putting a tiny drop of purple also will whiten it, but have not tried, as I do not understand the science of that.
DUH... this sounds so easy - that's probably why I never thought of it! already melted marshmallow - what a concept!
marshmallow creme - YOU ROCK !
I had the same problem with my MMF too. I bought some of the white coloring and added it to the MMF and it made it a really pretty white.
