Combine flour, water, oil, salt, and cream of tartar in a large saucepan over medium heat. Stir continuously until mixture starts to clump in the center on your spoon. This part usually takes about 5 minutes.
Remove from heat and add vetiver, wild orange, and tangerine essential oils- stir well to combine. If desired add food coloring and mix.
Grate orange/tangerine peel with a fine grater into your playdough mixture, it gives a tiny bit of texture but plenty of additional good smell!
Remove playdough from pan and place on a floured surface, allow it to cool until it is comfortable to the touch.
Knead for 2-3 minutes to incorporate all your color and essential oils, the dough will loosen up and become a softer texture after kneading.
Store in an airtight container when not in use.
