The prettiest, smoothest, best-smelling, and longest-lasting homemade playdoh ever!
Measure flour, salt, cream of tartar, water, & oil into a saucepan. You can easily double, triple, or even quadruple the recipe for a bigger batch.
Place saucepan on stove with burner set to low and begin stirring. The time it takes to turn into playdoh varies, but expect it to take between 10 and 20 minutes to become solid. A bigger batch will take longer.
Once the mixture begins to thicken and look less lumpy, add the food coloring and essential oil. It is not necessary to measure--just keep adding color and scent until it looks and smells good.
Keep stirring. If your kids are old/careful enough you can help them stir until it gets too thick. Once larger lumps begin to form, you’ll know you are getting close. Keep stirring!
Towards the end it will begin to get really thick and difficult to stir. Don’t worry if there are small lumps in the dough. It will be sticky but keep stirring. The play dough is done when it pulls away from the sides and all sticks together in one big lump.
Set on silicone mat or other heat-proof surface to cool. If dough seems too sticky you can knead it with a little flour.
To add sparkles, sprinkle dough generously with glitter, then knead dough until sparkles are evenly dispersed, adding more glitter if necessary.
Repeat process for additional colors; store in airtight container or bag.
