Here's the clay equivalent of comfort food: a sturdy, nubbly dough that provides hours of smushing and sculpting. It dries rock hard overnight and makes convincingly Jurassic-looking figures and pretty, earthy beads.
Allow finished creations to air-dry overnight. Leftover clay can be refrigerated in a ziplock bag for up to three days.
Stir together all the ingredients in a large bowl, adding more flour if necessary, until the dough forms a lump. For colored clay, you can add drops of food coloring to the water before combining it with the dry ingredients.
Knead it on a floured surface, adding flour as needed, until it is smooth and not too sticky.
