1 cup flour
2 teaspoons cream of tartar
1/2 teaspoon salt
1 cup water
1 tablespoon vegetable oil
1 teaspoon vanilla or any essential oil, optional
about 15 drops of food coloring, color of your choice
Cook all ingredients in a medium sauce pan, over medium heat, stirring real hard until mixture forms a ball. About 4 minutes. Remove from pan and let sit for about five minutes. Knead briefly and the dough is ready to use. Store in airtight container in refrigerator.
I usually split the dough into two pots to mix in the coloring and scent to get two colors out of each batch. You can keep this out of the fridge, I use this same recipe to make playdough for my classroom and we would keep it in the cabinet. After a few months it can start to smell funny(not sure if mine was from all the kids playing with it or just the dough getting old). Since it's so cheap to make, when it starts to not smell so good, we just chuck it and start over.
