Stir together the flour, salt, cream of tartar, ginger, cinnamon and nutmeg in a large pot. Next add the water and oil. If you want to add food coloring, mix in the the color now as well. I did not add food color for this playdough.
Cook over medium heat, stirring constantly. Continue stirring until the dough has thickened and begins to form into a ball.
Remove from heat and then place onto wax paper. Allow to cool slightly and then knead until smooth. If you’re adding colors after, divide the dough into balls (for how many colors you want) and then add the dough into the quart sized bags. Start with about 5 drops of color and add more to brighten it. Knead the dough, while inside the bag so it doesn’t stain your hands.
Once it’s all mixed together you’re ready to PLAY. Use cookie cutters and rolling pins and let your kids make different shapes. Store in an airtight container up to 1 month.
