The Abqaiq Cookbook - 1973
2 cups flour
1 cup salt
½ to ¾ cup water
2 tbsps. Powdered alum*
Mix flour, salt and alum in a bowl. Slowly mix in water. When the dough is thick and soft like modeling clay, it is ready to use. Either put food coloring or Tempera paint in while clay is wet or model as is and paint when dry. Dries in 24 hours.
*Small amounts of play dough can be made without alum.
