Knead It Together
Once it’s too solid to stir, pour your marshmallow fondant mixture out onto a flat work surface that’s been lightly dusted in more icing sugar. Keep kneading your mixture until it all comes together.
Note: You want the fondant to have some elasticity so that the it doesn’t break. If you find your fondant to be too tough, add in some more water. Or, if it’s too runny, simply add more icing sugar to the mixture and continue kneading.
