If you use a percentage of salt in relation to your meat it will never be too salty even if you leave in the cure for years. So in my case I put 2% salt to my pork belly, some like less or more, but once you figure out your sweet spot it will be perfect every time with no soaking or pre-tasting required. As processhead noted that’s too much salt for sure. 2% is 45 grams and 2.25% is 50 grams. 1/3 cup is approximately 91 grams which is almost double at 4%. For reference most dry cured meat is only 3%.
