How to mix salt

[IanWR]

I hope this isn't thread hijacking, but there is no need to mix dry salt before mixing it with water, is there? Hopefully some of our elder statesmen can answer definitively.

It reminds me of the community health nurse who did our daughters first immunization who told us to make sure to shake the container of formula powder before mixing since it contains iron that can settle to the bottom. I didn't, and never seemed to find a layer of iron filings at the bottom. I guess we were lucky.
