increase the temperature of the solution and add more salt

Explanation: the solubility of most solids (like salt) in water rises with temperature, so heating lets you dissolve more salt. If you then cool the solution gently without disturbing it, it can remain supersaturated (contains more dissolved salt than it would at the lower temperature). Changes in pressure have little effect on the solubility of solids in liquids.
