Mix with a spoon or your hands until a dense dough forms.
Knead until fully mixed and soft. Salt dough will be a similar consistency to playdough and bread dough mixed together.
If dough is too dry, add small amounts of water; if it’s too wet and sticky, add small amounts of flour. Salt dough is very easy to "fix" if you find your ratios to be off.
Notes
While salt dough is non-toxic and will likely not cause harm if small amounts are consumed, it is not edible. Uncooked all-purpose flour is not safe to eat, plus this dough will not taste good at all! As with pretty much all activities done with younger children, make sure to supervise so the dough does not get eaten.If you want to dry out your salt dough creations, the best method is to do this by baking in the oven. Flat designs that are roughly 1/4-inch in thickness should be placed on a baking sheet lined with parchment paper. Bake at 200°F for 2-3 hours.You can also let salt dough air dry. If you go this route, place your creations on a cooling rack or other surface so air can circulate all around the project. Depending how thick your creation is, this will usually take 1-2 days to dry.
