I don't know whether I've ever posted this recipe before, but I make homemade playdough for my students all of the time! Cheap, easy, infinitely customizable, and lasts so much longer than the stuff in the little yellow jars!
You will need . . .
1 cup flour
1/2 cup salt
2 tbsp oil
2 tsp cream of tartar
1 cup water
any food coloring or scent you'd like to use (unsweetened Kool-Aid packets add a lot of bright color and fruity fragrance! Any extracts or spices work well, too -- I especially like adding lots of cinnamon to orange playdough in the fall!)
(And feel free to use cheap, non-organic ingredients. No one will be eating this!)
(Or should I say, no one SHOULD be eating this?????)
Combine all of your ingredients in a saucepan. (I made a quadruple batch last night, as I have 20 kids in my class!)
Stir over low heat. (This will take quite a while, and will get pretty stiff and thick near the end. Use your best, strongest, wooden spoon!)
When the playdough begins to pull away from the sides of the pan and hang together in a big lump, it's done!
Knead while warm until smooth. I usually wear my kitchen gloves for this task, as the dough is usually pretty hot at first.
Store the playdough in the fridge in a ziploc baggie or sealed plastic container for maximum life. :)
