What will happen if I increase my brine from 1 cup of salt per gal. to 2 cups per gallon of water when I brin

Get some FRESH eggs. Take 1 of the eggs IN THE SHELL, and don't crack it. Wash it, and put it in the water. It will drop to the bottom. Start adding salt, and keep track of how much you use. When the egg floats to the top, add an equal amount of sugar. Take the egg out, rinse it, and put it back in the fridge. (It's still good to use for other things.) That's how you can tell how much salt to put in a brine.
