This is the recipe that I use, simply because it makes the dough last longer than the simplest recipe. I found it at Amazing Moms.
Salt: 1 1/2 cups
Water: 3 cups
Vegetable Oil: 2TB.
Cream of tartar: 1TB.
Food coloring: few drops or unsweetened "Kool-Aid" 1pkg.
Mix ALL of the ingredients in a large saucepan.
Cook over medium low heat, until the dough comes away
from the edges of the pan and it becomes difficult to move the spoon. Remove from heat. Cool until it can be handled.
Place on counter or wax paper knead 3-4 times.
Store in an air tight container.
I usually try and make two colors, that way each kid gets there own, and it cuts down on the fighting.
Enjoy and have fun!!
