To make the snowskin’s chewy and soft exterior, mix the following ingredients with a whisk: 2 tablespoon wheat starch, ¼ cup rice flour, ¼ cup glutinous rice flour (mochiko flour), ½ cup milk, 1 tablespoon condensed milk, and 1 tablespoon neutral cooking oil. Mix until there are no clumps and the batter is smooth. Cover the bowl with a plate, plastic wrap or a cheese cloth to prevent water from coming in to the batter when steaming.
¼ cup rice flour, ¼ cup glutinous rice flour, ½ cup milk, 1 tablespoon condensed milk, 1 tablespoon neutral cooking oil
Boil water on medium-high heat in a large pot. Once water is boiling, place covered bowl on a steaming rack. Steam for 20 minutes.
After steaming, take the bowl out of the pot and cool for at least 10 minutes. Make sure the snowskin is not too hot to touch. Knead the snowskin dough until it becomes soft and easy to move around similar to play-doh!
(OPTIONAL) To make colored dough, roll the dough in a ball. Then, split the dough in half. Use half for white dough. Then, split the other half in quarters. Add ¼ teaspoon matcha powder (or food color of choice) to the dough and knead until it turns green. Add ¼ teaspoon ube food coloring to the other piece of dough and knead until it turns purple.
¼ teaspoon matcha powder (optional), ¼ teaspoon ube extract (optional)
