You actually use more sea salt in cooking than one would use kosher or table salt.
Only salt water fish. But if you have a pet salt water fish then it is better to use sea salt and research on how much sea salt to use.
Yes, sea salt is perfectly ok for use in cooking. Some will even say sea salt is better for you.
ummm......Carefully
Salt is extracted from salt mines or sea waters and refined for edible use.
Any type of salt, refined and conditioned.
Yes. Natural sea salt. Table salt can have things added to it and that can be bad for the piercing. Its just the safest bet :)
Use sea salt?
Because its saltierr :]
Yes
You just use the same amount.
It depends. Check the back of the machine. There will be a sticker that says the voltage and current rating. It may already say the wattage, but if it doesn't, multiply the voltage by the current. Remember milliamps are .001 A. So if the voltage rating on the slushy machine is (I doubt the current is this low) 120 and the current is 500mA, then the wattage is 60W. Its likely that the voltage rating be something like 125 and the current 4A, but I've never used one, so just use the P=VI formula.
