are there any normal-ish food recipes for which the salt and water could be replaced by seawater?

random page on the internet that is probably wrong claims that's about (cw: stupid american units) 1 1/4 tsp salt per cup of water

also would it taste interesting, or just terrible

@pho4cexa Very late to the party, but was told by a prepper friend living by the sea that it more or less only works for potatoes. Even pasta gets too salty, apparently. Also a good idea to check pollution levels of your specific body of water, plenty of nasty junk from ships even when they're not leaking 🙄
