Yeah, I know posting a “recipe” for salt is lame, but not as lame as paying $3 for a tiny jar of “Popcorn Salt.” Also, I know that salt is not a snack (at least not for most people), but I don’t have a better categoty for it, and it goes with the popcorn recipe, so I put it here . . . .
Popcorn Salt is just Kosher Salt that’s been ground with a finer particle size to stick to the popcorn better and you can make your own, pretty much for free.
Kosher Salt can be easily ground in a mortar and pestle, and although it’s also possible to do in a food processor with a metal blade, it will severely scratch the work bowl (think frosted glass) as well as dull the blades.
Directions:
Put the desired amount of salt in the bowl, and grind until really fine.
Use a stone mortal and pestle. If you don’t have one, buy one. They’re about $10 at any Asian grocery store.
Note that the reason I specify Kosher Salt is because it contains no additives like iodine, that can effect the flavor of the food.
