I have not made this recipe in ages, so I checked it on the internet and found it hasn’t changed.
This seems like a good project for a family when everyone is stuck indoors.
Cooked Salt ClayRecipe
2 Cups of Flour
2 Cups of water
1 Cup of salt
2 Tablespoon vegetable oil — The oil will make the dough a little easier to knead and work with but some recipes omit it.
1 Tablespoon cream of tartar — The cream of tartar makes this dough last 6 months or longer, so resist omitting it. But if you are making ornaments that you are going to dry right away, the cream of tartar isn’t needed.
In a large saucepan mix the flour, cream of tartar, and salt; add oil and water.
Cook over medium heat five minutes, stirring constantly. Your arm may tire as mixture thickens—having a helper is nice.
It is finished when the dough clings to the spoon and refuses to be moved. Take care not to scorch.
Remove from heat and cool a bit. Divide into fourths and add food coloring. Knead.
After play period, roll dough in a large ball, or in four balls if you have colored them, place them in plastic bags, and store them in the refrigerator. If sticky when removed, add a little flour.
If you made cookie cutter ornaments, let them air dry for 1 to 3 days then they can be painted.
