I am making a small batch of MMF (the one that calls for 1 cup of marshmallows) and want to add the food coloring to the melted marshmallows rather than kneading it in. Approximately how much do you think I'll need to make it a vibrant Christmas red?
Fondants lighten slightly as they dry so tint it until you are happy w/the color. Be aware that paste colors (& maybe even gels) will make the fondant somewhat sticky & soft
There is really no way to advise how much you will need....I'd guess maybe 1/4 of a small 'pot'?
