Gluten Free Play Dough - cooking recipe

Ingredients

1 cup rice flour
1 cup cornflour
1 cup salt
4 teaspoons cream of tartar
2 tablespoons vegetable oil
2 cups water
food coloring

Preparation

Mix base ingredients in a large measuring pitcher.
Heat one cup of the resulting white mixture in a small saucepan. and add some food colouring (a few drops at a time) to reach the desired colour.
Stirring constantly with a wooden spoon, cook over low heat for about 5 minutes. Consistency will be very runny at first but once it starts to thicken mixture will firm up quite fast.
Remove from heat and knead to remove lumps (if any).
Repeat with rest of mixture. 1 cup of the mixture will yield approximately 1 small canister of Gluten-free Play Dough (like the standard sets with a few colours you buy in the store).
Given prep/cooking time is for one colour.
