Result: You miss out on an easy way to cut 20% of your added salt.

Kosher and table salt are chemically the same. But the larger grain size of kosher salt actually works to your advantage. Tiny grains of table salt tend to pack down in the spoon, leaving less air. Coarse flakes and crystals pile up like little, rough rocks, with more air between the pieces. That adds up to 20% sodium savings.

What to do: Have fun exploring the new sea and rock salts now on the market. Stronger flavor means you can use less, too.
