In a large heavy-bottomed pot whisk together flour, salt, and cream of tarter.

Pour water and vegetable oil over the flour mixture. Stir until the mixture turns into a thick paste. Make sure you get into the edges of the pot to get any hidden pockets of flour.

If you’re turning the play dough all one color, then add in the food coloring now.

Place the pot on a burner and set to medium heat.

Stir the mixture constantly until it has thickened and starts to form together. Remove the pot from the heat and transfer the play dough to a piece of plastic wrap.

Cool the mixture until it’s comfortable to handle (especially for the kids). Then knead it until smooth, about 1 minute.

Determine how many different colors you’re going to turn the play dough. Distribute the play dough to as many quart-sized bags as the number of colors you have.

Place 4-5 drops of food coloring into the center of a dough ball. Place the dough ball inside of a quart-sized Ziploc-bag and knead until the color is distributed evenly.

Knead in glitter (if using).

Now you’re ready to play with the playdough! Keep the dough balls stored in air-tight containers or Zip-loc bags. If properly stored, the playdough will keep for 2-3 months.
