Regardless of the recipe you choose, you will need:
Powdered sugar – as much as the dough absorbs;
Marshmallows – 200 g;
Water – 2 tbsp;
Butter – 10-15 g;
Food coloring to change the mixture's color.
First, place the marshmallows in a deep bowl, add a small piece of butter (you can substitute it with lemon juice for a slight tang), and microwave for 40 seconds. The fondant will turn out tender and pliable. Once the marshmallows have melted slightly, gradually fold in the sifted powdered sugar. Keep adding it until the dough resembles modeling clay. Wrap the finished mass in plastic wrap and place it in the freezer for 40 minutes, after which it will be ready to use.
