From CigarsInternational:
Dampen the salt with water. Do not put so much in that the salt gets "sloppy". You want a damp pile of salt in the bottle cap.
From somewhere else on the web:
Place about a teaspoon of salt in the bottle cap and drip just enough distilled water on the salt to get it wet. If done right, it should have a thick, pasty consistency, not watery. Place the cap and the hygrometer face-up in the baggie, so you can read it.
