To be honest I just splash some in there. Someone here on BYC mentioned it. We use an electric skillet, I just fill it with water to cover the eggs, usually boil around 2 doz at a time. I would estimate that it is around .5 tablespoon salt and 1 to 1.5 tablespoons of baking soda.how much salt and baking soda to how many eggs or pot size?
