In a large saucepan, whisk together the flour, salt, and cream of tartar.
Add the water and vegetable oil to the saucepan and mix until well combined.
Place the saucepan over medium heat and cook the mixture, stirring continuously, until it forms a thick dough-like consistency.
Remove the saucepan from the heat and let the dough cool for a few minutes.
Divide the dough into equal portions and knead each portion until smooth.
If desired, add a few drops of food coloring or liquid watercolors to each portion and knead until the color is evenly distributed.
Optional: Add a few drops of essential oils for a delightful scent.
