**The amount of water and maple syrup depends on your preferred sweetness of the marshmallow. The water and maple syrup should combine to make 2 cups of liquid. So for a less sweet marshmallow you would use the recipe above (1.5 cups water and 1/2 cup maple syrup). If you want a sweet marshmallow, you can use 1 cup of maple syrup and 1 cup of water. If you want somewhere between those two extremes, just adjust the ratios accordingly.
