Best Playdough Ever, really... Ever!

Ok, I realize this is not a great photo, but BELIEVE ME... I have tried and tried playdough recipes... This one has the consistency of the store bought playdough (minus the smell...) I made this one red with red glitter (and raspberry koolaid for good smell) for Chinese New Year and Valentine's Day.

2 c. all purpose flour
1/2 c. salt
1 pk Unsweetened koolaid, any flavor
4 tsp. cream of tartar
2 c. water
2 T. corn oil
Mix all the ingredients together in a large saucepan. Cook and stir over low heat until the mixture thickens an dthe bottom is just starting to crust up, about 15 minutes. The dough will be very stiff and hard at this point.
Turn the dough out onto a large cookie sheet and let it cool. When cool, knead until smooth. Store in a covered container.
Let the fun begin!
