Okay, I’m still confused about a few details not mentioned yet. From the posts so far, it appears that in the US, Kosher salt should be called Koshering salt, because it’s grain size makes koshering easier. There’s also a reference to TV cooks, to explain why non-Jews would use it for other cooking.
Question: Don’t you use different types of French-named sea salt for “normal” (that is, non-Jewish observant) cooking? E.g. when I want to go beyond normal ordinary table salt, into the direction of star-cooking, I’d buy Fleur de seul (Flower of Salt), the most expensive salt available (it’s the thinnest crust and only forms if there’s no wind, and is harvested by hand with care), or to coarse grain salt for making salt crust for fish or similar.
We have several Jews of different strictness here, and it was said that salt is always kosher. That surprises me, because I thought I read somewhere else that for the strict Jews (Orthodox) some normal food has become non-kosher because of the change in food preparation through industry; one example given was salt (or similar?) filtered through an animal product.
Question: Am I confusing things again, or is salt generally kosher, but non-kosher with the wrong industry processing?
Lastly, if the “Christian salt” is blessed by a priest, some asked what would be the use of it. Now, I’m not a catholic, but in some of the older books from the 1950s I recently skipped, they mentioned that if a oiling for an ill person together with a service or a similar religious special visit by a priest into a home is made, you (the home owner) should provide among other (clean white table cloth, water to wash and purify with, candles) is salt, that the priest blesses and then uses for purification. (Salt has an ancient tradition in that regard, because it prevented food from spoiling).
Question to the Catholics here: is that still done today? So would commercially bought blessed “Christian salt” be useful in a normal household without warding off zombies or vampires?
Aside: Now I remember that in Japan, at the start of each Sumo match, the priest also throws salt into the air for purification of the ring. How big is the market for Buddhist/Shinto salt, and can the guy get a foot in there, too?
