Place the flour, salt and Cream of Tartar in a bowl and mix together.
In a separate bowl mix together the water, oil and 1tsp of your chosen Dr. Oetker Colour gel.
Pour the water ingredients into the flour mixture and stir until the mixture comes together to form a dough, the dough will be quite sticky.
Place the dough on a floured surface and knead until it becomes less sticky and a nice consistency to model with, adding more flour to the surface if needed.
Store the playdough in an airtight container when not being used.
This recipe makes one portion of playdough. Make the recipe a few times using a different Colour Gels and create lots of bright colourful playdough!
