In a large, heat-safe mixing bowl, whisk together the flour, salt, and cream of tartar.
Pour the boiling oil, water and peppermint into the flour mixture. If you're making the dough red, you can add a few drops of the food coloring.
Using a rubber spatula or wooden spoon, mix all the ingredients until it comes together.
Once the dough is cool enough to touch, turn out on your work surface and knead it until it's smooth.
