I've been trying to find things for the kiddos to do that keeps all ages
1 c flour
1/2 c salt
1 c water
2 tsp cream of tartar
1 T cooking oil
Combine all ingredients and cook over low heat until thick. Don't get discouraged if it takes too long, just keep stirring! Once, it's firmed I like to give the dough a good kneading on a well-floured surface until it's a good consistency. Then simply add the food coloring of your choice! Quick and easy.
It might not look like in the photo, but there is a difference between the purple and the blue!
