Cornstarch dough

I made my own cornstarch dough because Levi is allergic to coloring, and I think play doh feels kinda gross. This dough has a nice texture to it and doesnt dry out your hands like salty homade playdough can.
I store it in the fridge because of the weather here (to prevent mold!), and it lasts a long time. You can also roll it out and bake it in the oven to make ornaments and things. (low temp for an hour or so). It can be painted once its dry.

Here is the recipie:

2 cups baking soda
1 cup cornstarch
1 1/4 cups water
Food coloring (optional, you can also use powdered tempra paint, or unsweetened koolaid)

Mix baking soda and cornstarch together in a saucepan. Gradually stir in water. Bring to a boil over medium heat, stirring constantly until mixture begins to thicken. Remove from heat while dough is still easy to stir. Do not overcook. Turn out on platter and cover with a damp cloth. When cool enough to handle, knead until smooth, adding water if dough crumbles. If desired, knead in food coloring.
