Ouch. Yes, soy sauce is very salty, one needs to be careful! Whenever I use some, I don’t use other salt or just a pinch. Except when I add it later but I only pour a little then…
If we have oversalted meat, I use eggs or sour cream or whatever sounds right. I can’t eat too salty stuff or if I can, it’s still horrible instead of a joyous meal, I must balance it out. Thankfully there are ways. Like eggs. My sponge cake buns have no added salt so they are especially good in this situation - or in the way more frequent one when I buy some too salty processed meat item. Even many cheeses are too salty. Cream cheese is especially so.
My salt need is about the same all the time and if it comes to ideal saltiness, I do have a range but it starts at zero and ends up around 1%…? Depends on the food, fried pork is best if I use 1g salt per a pound of raw meat, eggs don’t really need any but a tiny bit is better. If something is too salty, I need to add something. If I only ate meat, I would have lightly salted meat at hand at all time. Like the inside of my roasts.
Oversalting usually happens with the liquid below my roasts. I don’t use too much salt but if it’s not overly tiny, it ends up in that liquid/jelly, inevitably, leaving my meat not salty enough. Still not necessarily a problem as I probably eat the jelly with the unsalted insides eventually But my sponge cake buns help too. Still. I do love if I can just eat the jelly alone if I wish… I will learn again, too much time passed since I was in a habit of making roasts but I love the idea again. It just needs 2 hours for my pork to get ready… Not always convenient.
